* net/macb: support reversed hw addrJoachim Eastwood2012-11-07
| | | | | | | | | | | This is used on one AT91RM9200 board where a bootloader stores the Ethernet address in the wrong order. Support this on macb so address setting functions can be shared with the at91_ether driver. Signed-off-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net/macb: check all address registers setsJoachim Eastwood2012-11-07
| | | | | | | | | | | | | | The macb driver in u-boot uses the first register set while the at91_ether driver in u-boot uses the second register set. By checking all register set, like at91_ether does, this code can be shared between the drivers. This only changes behavior on macb if no vaild address is found in the first register set.

* mlx4: change TX coalescing defaultsEric Dumazet2012-11-07
| | | | | | | | | | | | | | | | | | | | | | | mlx4 currently uses a too high tx coalescing setting, deferring TX completion interrupts by up to 128 us. With the recent skb_orphan() removal in commit 8112ec3b872, performance of a single TCP flow is capped to ~4 Gbps, unless we increase tcp_limit_output_bytes. I suggest using 16 us instead of 128 us, allowing a finer control. Performance of a single TCP flow is restored to previous levels, while keeping TCP small queues fully enabled with default sysctl. This patch is also a BQL prereq.

| | | | | | | | | | This patch gets the runtime PM reference count before calling usbnet_{read|write}_cmd, and puts it after completion of the usbnet_{read|write}_cmd, so that the usb control message can always be sent to one active device in the non-PM context.

* net: calxedaxgmac: ip align receive buffersRob Herring2012-11-07
| | | | | | | | | | | | | | | | On gcc 4.7, we will get alignment traps in the ip stack if we don't align the ip headers on receive. The h/w can support this, so use ip aligned allocations. Cut down the unnecessary padding on the allocation. The buffer can start on any byte alignment, but the size including the begining offset must be 8 byte aligned. So the h/w buffer size must include the NET_IP_ALIGN offset. Thanks to Eric Dumazet for the initial patch highlighting the padding issues.

* net: calxedaxgmac: use raw i/o accessors in rx and tx pathsRob Herring2012-11-07
| | | | | | | | | | | | The standard readl/writel accessors involve a spinlock and cache sync operation on ARM platforms with an outer cache.

* atp: remove set_rx_mode_8012()Paul Bolle2012-11-03
| | | | | | | | | | | | | | | | | Building atp.o triggers this GCC warning: drivers/net/ethernet/realtek/atp.c: In function ‘set_rx_mode’: drivers/net/ethernet/realtek/atp.c:871:26: warning: ‘mc_filter[0]’ may be used uninitialized in this function [-Wuninitialized] GCC is correct. In promiscuous mode 'mc_filter' will be used uninitialized in set_rx_mode_8012(), which is apparently inlined into set_rx_mode(). But it turns out set_rx_mode_8012() will never be called, since net_local.chip_type will always be RTL8002. So we can just remove set_rx_mode_8012() and do some related cleanups.

* macb: Keep driver's speed/duplex in sync with actual NCFGRVitalii Demianets2012-11-03
| | | | | | | | | | | | | | | When underlying phy driver restores its state very fast after being brought down and up so that macb driver function macb_handle_link_change() was never called with link state "down", driver's internal representation of phy speed and duplex (bp->speed and bp->duplex) didn't change. So, macb driver sees no reason to perform actual write to the NCFGR register, although the speed and duplex settings in that register were reset when interface was brought down and up. In that case actual phy speed and duplex differ from NCFGR settings. The patch fixes that by keeping internal driver representation of speed and duplex in sync with actual content of NCFGR.

* vhost-net: select tx zero copy dynamicallyMichael S. Tsirkin2012-11-02
| | | | | | | | | | | | | | | | | Even when vhost-net is in zero-copy transmit mode, net core might still decide to copy the skb later which is somewhat slower than a copy in user context: data copy overhead is added to the cost of page pin/unpin. The result is that enabling tx zero copy option leads to higher CPU utilization for guest to guest and guest to host traffic. To fix this, suppress zero copy tx after a given number of packets triggered late data copy. Re-enable periodically to detect workload changes. Signed-off-by: Michael S.
