* | e1000e: cleanup: use goto for common work needed by multiple exit pointsBruce Allan2012-02-13
| | | | | | | | | | | | | | | | | | | | | | There are two exit points of e1000e_write_nvm_spi() which require the nvm->ops.release() function pointer called just before exiting. Consolidate the two duplicate pieces of common work with a goto. With this change, the value ret_val will need to be returned instead of 0.

* | rename dev_hw_addr_random and remove redundant secondDanny Kukawka2012-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Renamed dev_hw_addr_random to eth_hw_addr_random() to reflect that this function only assign a random ethernet address (MAC). Removed the second parameter (u8 *hwaddr), it's redundant since the also given net_device already contains net_device->dev_addr. Set it directly. Adapt igbvf and ixgbevf to the changed function. Small fix for ixgbevf_probe(): if ixgbevf_sw_init() fails (which means the device got no dev_addr) handle the error and jump to err_sw_init as already done by igbvf in similar case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change combines a number of post-DMA Rx packet processing functions into a single function. The advantage of this is that it combines most of the Rx descriptor processing into one spot so it should all be warm in the cache.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes it so that we always clear the status/error bits in the Rx descriptor in the allocation path instead of the cleanup path.

| * | ixgbe: Address fact that RSC was not setting GSO size for incoming framesAlexander Duyck2012-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is meant to address the fact that RSC has not been setting the gso_size value on the skb. As a result performance on lossy TCP connections was negatively impacted. This change resolves the issue by setting gso_size to the average size for incoming packets.

| * | ixgbe: Minor refactor of RSCAlexander Duyck2012-02-10

First I had left the use of the next and prev skb pointers floating around in the code and they were overdue to be pulled since I had rewritten the RSC code in the out-of-tree driver some time ago to address issues brought up by David Miller in regards to this. I am also now defaulting to always leaving the first buffer unmapped on any packet and then unmapping it after we read the EOP descriptor. This allows a simplification of the path with less branching. Instead of counting packets received the code was changed some time ago to track the number of buffers received. This leads to inaccurate counting when you compare numbers of packets received by the hardware versus what is tracked by the software. To correct this I am revising things so that the append_cnt value for RSC accurately tracks the number of frames received.

| * ixgbe: ethtool: stats user buffer overrunJohn Fastabend2012-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the number of tx/rx queues changes the ethtool ioctl ETHTOOL_GSTATS may overrun the userspace buffer. This occurs because the general practice in user space to query stats is to issue a ETHTOOL_GSSET cmd to learn the buffer size needed, allocate the buffer, then call ETHTOOL_GSTIRNGS and ETHTOOL_GSTATS. If the number of real_num_queues is changed or flow control attributes are changed after ETHTOOL_GSSET but before the ETHTOOL_GSTRINGS/ETHTOOL_GSTATS a user space buffer overrun occurs. To fix the overrun always return the max buffer size needed from get_sset_count() then return all strings and stats from get_strings()/get_ethtool_stats(). This _will_ change the output from the ioctl() call which could break applications and script parsing in theory. I believe these changes should not break existing tools because the only changes will be more {tx|rx}_queues and the {tx|rx}_pb_* stats will always be returned. Existing scripts already need to handle changing number of queues because this occurs today depending on system and current features. The {tx|rx}_pb_* stats are at the end of the output and should be handled by scripts today regardless. Finally get_ethtool_stats and get_strings are free-form outputs tools parsing these outputs should be defensive anyways. In the end these updates are better then having a tool segfault because of a buffer overrun.

So, when upper layer driver, e.g., FCoE protocol stack is monitoring the netdev event of NETDEV_UNREGISTER and calls back to LLD ndo_fcoe_disable() to remove extra queues allocated for FCoE, the associated txq sysfs kobjects are already removed, and trying to update the real num queues would cause something like below: ...

| * ixgbe: Fix broken dependency on MAX_SKB_FRAGS being related to page sizeAlexander Duyck2012-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an issue in which RSC will generate corrupted frames when PAGE_SIZE is larger than 8K. Specifically it looks like that in 2.6.39 a change was made so that GRO would always have at least 16 frags available for coalescing, but the ixgbe RSC logic was not updated. As such the RSC feature would generate a frame larger than 64K and then overflow the value in the IP length field. To correct that I am now basing things on the PAGE_SIZE.

| * ixgbevf: Fix mailbox interrupt ack bugGreg Rose2012-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove jump to out label that was skipping over code to replace the ack bit in the mailbox cache variable. This was causing driver mailbox routines that poll for the PF to ack a message to time out which would in turn cause all other mailbox messages to fail. Also replace the mailbox cache variable message indication bit when a message is found so that other functions that choose to poll for a mailbox message from the PF won't miss it.

* | ixgbe: Add module parameter to allow untested and unsafe SFP+ modulesPeter P Waskiewicz Jr2012-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The X520 family of network devices, with the 82599 chip, support a small number of Intel-verified SFP+ modules on their NICs. To maintain stability and quality, the current devices restrict untested 3rd party SFP+ modules. This patch introduces a module parameter for ixgbe to allow these untested modules at the user's peril. It also includes a warning to the syslog alerting users that the modules aren't supported, and results may vary.

* | e1000e: split lib.c into three more-appropriate filesBruce Allan2012-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic lib.c file contains code relative to the various MACs, NVM and Manageability supported by the driver. This patch splits the file into three which are specific to those areas similar to how the PHY-specific code is in phy.c and code specific to the 80003es2lan, 8257x, and ichX MAC families are in their own files. The generic code that is applicable to all MAC/PHY parts supported by the driver remains in netdev.c, param.c and ethtool.c files. No change in functionality, just moving code around for ease of maintenance, with some whitespace and other checkpatch cleanups.
