* | fm10k: Add support for bulk Tx cleanup & cleanup boolean logicAlexander Duyck2016-04-21
| | | | | | | | | | | | | | | | | | This patch enables bulk free in Tx cleanup for fm10k and cleans up the boolean logic in the polling routines for fm10k in the hopes of avoiding any mix-ups similar to what occurred with i40e and i40evf.

* | fm10k: remove debug-statistics supportJacob Keller2016-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | This change fixes an (ab)use of the ethtool stats API, which could result in corrupt memory or misleading stat output. The ethtool stats API is not robust enough to handle varying number of statistics due to how it requests the size and allocates memory. Remove the poorly conceived support originally added for extra debug statistics. In the future, a new stats API may open up the ability to display these statistics.

* | fm10k: add helper functions to set strings and data for ethtool statsJacob Keller2016-04-21
| | | | | | | | | | | | | | | | | | | | | | | | Reduce duplicate code and the amount of indentation by adding fm10k_add_stat_strings and fm10k_add_ethtool_stats functions which help add fm10k_stat structures to the ethtool stats callbacks. This helps increase ease of use for future stat additions, and increases code readability.

| * e1000: Double Tx descriptors needed check for 82544Alexander Duyck2016-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 82544 has code that adds one additional descriptor per data buffer. However we weren't taking that into account when determining the descriptors needed for the next transmit at the end of the xmit_frame path. This change takes that into account by doubling the number of descriptors needed for the 82544 so that we can avoid a potential issue where we could hang the Tx ring by loading frames with xmit_more enabled and then stopping the ring without writing the tail. In addition it adds a few more descriptors to account for some additional workarounds that have been added over time.

| * e1000: Do not overestimate descriptor counts in Tx pre-checkAlexander Duyck2016-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code path is capable of grossly overestimating the number of descriptors needed to transmit a new frame. This specifically occurs if the skb contains a number of 4K pages. The issue is that the logic for determining the descriptors needed is ((S) >> (X)) + 1. When X is 12 it means that we were indicating that we required 2 descriptors for each 4K page when we only needed one. This change corrects this by instead adding (1 << (X)) - 1 to the S value instead of adding 1 after the fact. This way we get an accurate descriptor needed count as we are essentially doing a DIV_ROUNDUP().

Alex fixes igb where we were casting the MAC address as __beXX and then passing it into le32_to_cpu, when we could simply cast as __lexx to maintain consistency since it is already little endian. Then enabled bulk free in transmit cleanup for igb. John Holland enables igb to pickup the MAC address from a device tree blob when CONFIG_OF has been enabled. Doron Shikmoni fixes a bug in the output of "ethtool -m ethX" where the data byte appeared duplicated. Stefan fixes up e1000 and e1000e ethtool offline tests which were calling dev_close() which causes IFF_UP to be cleared which removes teh interface routes and some addresses, so use ndo_stop() instead. Jiri Benc cleans up some old links in the Kconfig for Intel drivers where we referred to a URL which is no longer valid. I am so glad Jiri has the time in his day to spend clicking on and testing all the URL links in the the kernel.

* | | i40e: Move HW flushAkeem G Abodunrin2016-04-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the HW flush routine to the end of the reset flow, after the completion of writing to the device VFLR registers- the benefit is to avoid problems in the passthrough routines.

* | | i40e: Leave debug_mask cleared at initShannon Nelson2016-04-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't set our internal debug_mask at startup unless we get specific signal to from the debug module parameter. This should take care of the issue with all the device capabilities getting printed even when we hadn't asked for the debug info.

* | | i40e/i40evf: Fix TSO checksum pseudo-header adjustmentAlexander Duyck2016-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With IPv4 and IPv6 now using the same format for checksums based on the length of the frame we need to update the i40e and i40evf drivers so that they correctly account for lengths greater than or equal to 64K. With this patch the driver should now correctly update checksums for frames up to 16776960 in length which should be more than large enough for all possible TSO frames in the near future.
