sungem: Spring cleaning and GRO support
This patch simplifies the logic and locking in sungem significantly: - LLTX is gone, all private locks are gone, mutex is gone - We don't poll the PHY while the interface is down - The above allowed me to get rid of a pile of state flags using the proper interface state provided by the networking stack when needed and overall simplify the driver a lot - Allocate the bulk of RX skbs at init time using GFP_KERNEL - Fix a bug where the dev->features were set after register_netdev() - Added GRO while at it Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: David S. Miller <davem@davemloft.net>
