2012-11-03atp: remove set_rx_mode_8012()Paul Bolle2-58/+2
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.

2012-11-03macb: Keep driver's speed/duplex in sync with actual NCFGRVitalii Demianets1-0/+2
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.

2012-11-02vhost-net: reduce vq polling on tx zerocopyMichael S. Tsirkin1-2/+12
It seems that to avoid deadlocks it is enough to poll vq before we are going to use the last buffer. This is faster than c70aa540c7a9f67add11ad3161096fb95233aa2e. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-11-02vhost-net: select tx zero copy dynamicallyMichael S. Tsirkin1-8/+53
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.

2012-11-02tun: report orphan frags errors to zero copy callbackMichael S. Tsirkin1-0/+1
When tun transmits a zero copy skb, it orphans the frags which might need to allocate extra memory, in atomic context. If that fails, notify ubufs callback before freeing the skb as a hint that device should disable zerocopy mode. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-11-02skb: report completion status for zero copy skbsMichael S. Tsirkin2-2/+2
Even if skb is marked for zero copy, net core might still decide to copy it later which is somewhat slower than a copy in user context: besides copying the data we need to pin/unpin the pages. Add a parameter reporting such cases through zero copy callback: if this happens a lot, device can take this into account and switch to copying in user context. This patch updates all users but ignores the passed value for now: it will be used by follow-up patches. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: David S.

2012-11-01net/macb: better manage tx errorsNicolas Ferre2-54/+113
Handle all TX errors, not only underruns. TX error management is deferred to a dedicated workqueue. Reinitialize the TX ring after treating all remaining frames, and restart the controller when everything has been cleaned up properly. Napi is not stopped during this task as the driver only handles napi for RX for now. With this sequence, we do not need a special check during the xmit method as the packets will be caught by TX disable during workqueue execution.

2012-11-01net/macb: clean up ring buffer logicHavard Skinnemoen3-73/+127
Instead of masking head and tail every time we increment them, just let them wrap through UINT_MAX and mask them when subscripting. Add simple accessor functions to do the subscripting properly to minimize the chances of messing this up. This makes the code slightly smaller, and hopefully faster as well. Also, doing the ring buffer management this way will simplify things a lot when making the ring sizes configurable in the future.
