igb: Replace LRO with GRO
This patch makes igb invoke the GRO hooks instead of LRO. As GRO has a compatible external interface to LRO this is a very straightforward replacement. Three things of note: 1) I've kept the LRO Kconfig option until we decide to enable GRO across the board at which point it can also be killed. 2) The poll_controller stuff is broken in igb as it tries to do the same work as the normal poll routine. Since poll_controller can be called in the middle of a poll, this can't be good. I noticed this because poll_controller can invoke the GRO hooks without flushing held GRO packets. However, this should be harmless (assuming the poll_controller bug above doesn't kill you first :) since the next ->poll will clear the backlog. The only time when we'll have a problem is if we're already executing the GRO code on the same ring, but that's no worse than what happens now. 3) I kept the ip_summed check before calling GRO so that we're on par with previous behaviour.
