* qeth: CCL-sequence numbers required for protocol ETH_P_802_2 onlyUrsula Braun2008-04-16
| | | | | | | | | | | | Symptom: slow CCL response time Problem: non-ETH_P_802_2 packets are not delivered to NDH for CCL. But CCL detects missing sequence numbers, which cause a serious performance problem with CCL. Solution: assign sequence numbers only to 802.2 packets.

* qeth: set lan_online flag after a received STARTLANUrsula Braun2008-04-16
| | | | | | | | | | | | | | | | | Problem: A STARTLAN command from the adapter may arrive while a qeth recovery is currently running with a failed qeth STARTLAN. Usually qeth schedules a recovery when receiving a STARTLAN command from the adapter. But another recovery scheduled while a recovery is already running never starts. Thus the qeth-administered lan_online flag remains zero in this scenario, even though the adapter-STARTLAN has happened. Solution: Set lan_online flag for a received STARTLAN from the adapter in case scheduled recovery does not start.

* qeth: allow qdio queue element addresses > 2GBUrsula Braun2008-04-16
| | | | | | | | | | | OSA-adapters do not have an address limitation for the qdio queue structures except the MAX storage level of the current processor. And due to a recent z/VM APAR there is no longer a restriction to allocate qdio structures below 2 GB.

* qeth: improve ip_list administration after deregister failuresUrsula Braun2008-04-16
| | | | | | | | | | | | | | | | | 1. ip_list handling after deregister failure of multicast address: If error code "MC Address not found" is returned do not re-add multicast address to ip_list. For other error codes readd multicast address at the end of function qeth_delete_all_mc. 2. ip_list handling after deregister failure or normal ip address: If error code "IP Address not found" is returned do not re-add multicast address to ip list. This is especially important in IP address takeover scenarios, to enable re-takeover of a taken over IP address.

* [netdrvr] tulip: Better MWI workaround for 21143 rev 65 chip errataPeter Horton2008-04-16
| | | | | | | | | | | | | This patch works around the MWI bug on the DC21143 rev 65 Tulip by ensuring that the receive buffers don't end on a cache line boundary (as documented in the errata). This patch is required for the MIPS based Cobalt Qube/RaQ as supporting the extra PCI commands seems to reduce the chance of a hard lockup between the Tulip and the PCI bridge.

* [netdrvr] tulip/winbond-840: don't let tulip.h symbol stomp oursJeff Garzik2008-04-16
| | | | | | | | | | | | | | | | winbond-840 shares tulip.h with the tulip driver, because they share many (but not all) of the same register definitions. This is useful for the register definitions, but not helpful when it comes to symbols that are shared among the tulip driver's C modules, but not meant to be shared outside that one driver. Thus, PKT_BUF_SZ is a symbol internal to tulip, but it was intruding upon a similar symbol in winbond-840's namespace. This was not a problem as long as the two symbols had the same value, but upcoming patches result in differing symbol values. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

* spidernet: fix error interrupt handlingIshizaki Kou2008-04-16
| | | | | | | | | | | | | | | | In addition to the value of GHIINT0STS, spidernet interrupt handler should check the values of GHIINT1STS/GHIINT2STS registers at the beginning of spider_net_interrupt() so as not to drop error interrupts. GHIINT1STS/GHIINT2STS registers indicates some of erroneous conditions in spidernet, and a few bits of GHIINT0STS register reflects these conditions. But GHIINT0MSK masks these bits, so you should check these conditions by reading GHIINT1STS/GHIINT2STS registers directly.

* [NET]: Do not allocate unneeded memory for dev->priv alignment.Pavel Emelyanov2008-04-16
| | | | | | | | | | | | | | | | | | | | | The alloc_netdev_mq() tries to produce 32-bytes alignment for both the net_device itself and its private data. The second alignment is achieved by adding the NETDEV_ALIGN_CONST to the whole size of the memory to be allocated. However, for those devices that do not need the private area, this addition just makes the net_device weight 1024 + 32 = 1068 bytes, i.e. consume twice as much memory. Since loopback device is such (sizeof_priv == 0 for it), and each net namespace creates one, this can save a noticeable amount of memory for kernel with net namespaces turned on. After this set the lo device is actually allocated from a size-1024 kmem cache on i386 box even with NETPOLL and WIRELESS_EXT turned on.
