2011-08-18net: fix IBM EMAC driver after rename.Tony Breeds33-129/+150
In commit 9aa3283595451ca093500ff0977b106e1f465586 (ehea/ibm*: Move the IBM drivers) the IBM_NEW_EMAC* were renames to IBM_EMAC* The conversion was incomplete so that even if the driver was added to the .config it wasn't built, but there were no errors). In this commit we also update the various defconfigs that use EMAC to use the new Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard. We do not explicitly select the Kconfig dependencies, as this would force EMAC on. Doing it in the defconfig allows more flexibility. Tested on a canyondlands board.

2011-08-18vlan: reset headers on accel emulation pathJiri Pirko1-0/+2
It's after all necessary to do reset headers here. The reason is we cannot depend that it gets reseted in __netif_receive_skb once skb is reinjected. For incoming vlanids without vlan_dev, vlan_do_receive() returns false with skb != NULL and __netif_reveive_skb continues, skb is not reinjected.

2011-08-17bonding:reset backup and inactive flag of slavePeter Pan(潘卫平)1-0/+18
Eduard Sinelnikov (eduard.sinelnikov@gmail.com) found that if we change bonding mode from active backup to round robin, some slaves are still keeping "backup", and won't transmit packets. As Jay Vosburgh(fubar@us.ibm.com) pointed out that we can work around that by removing the bond_is_active_slave() check, because the "backup" flag is only meaningful for active backup mode. But if we just simply ignore the bond_is_active_slave() check, the transmission will work fine, but we can't maintain the correct value of "backup" flag for each slaves, though it is meaningless for other mode than active backup. I'd like to reset "backup" and "inactive" flag in bond_open, thus we can keep the correct value of them. As for bond_is_active_slave(), I'd like to prepare another patch to handle it. V2: Use C style comment. Move read_lock(&bond->curr_slave_lock). Replace restore with reset, for active backup mode, it means "restore", but for other modes, it means "reset".

2011-08-17rps: Inspect GRE encapsulated packets to get flow hashTom Herbert1-0/+22
Crack open GRE packets in __skb_get_rxhash to compute 4-tuple hash on in encapsulated packet. Note that this is used only when the __skb_get_rxhash is taken, in particular only when the device does not compute provide the rxhash (ie. feature is disabled). This was tested by creating a single GRE tunnel between two 16 core AMD machines. 200 netperf TCP_RR streams were ran with 1 byte request and response size.

2011-08-16ethtool: Correct description of 'max_coalesced_frames' fieldsBen Hutchings1-13/+13
The current descriptions state that these fields specify 'How many packets to delay ... after a packet ...' which implies that the hardware should wait for (max_coalesced_frames + 1) completions before generating an interrupt. It is also stated that setting both this field and the corresponding 'coalesce_usecs' field to 0 is invalid. Together, this implies that the hardware must always be configured to delay a completion IRQ for at least 1 usec or 1 more completion. I believe that the addition of 1 is not intended, and David Miller confirms that the original implementation (in tg3) does not do this.
