Alexander Duyck adc810900a ixgbe: Refactor busy poll socket code to address multiple issues ... This change addresses several issues in the current ixgbe implementation of busy poll sockets. First was the fact that it was possible for frames to be delivered out of order if they were held in GRO. This is addressed by flushing the GRO buffers before releasing the q_vector back to the idle state. The other issue was the fact that we were having to take a spinlock on changing the state to and from idle. To resolve this I have replaced the state value with an atomic and use atomic_cmpxchg to change the value from idle, and a simple atomic set to restore it back to idle after we have acquired it. This allows us to only use a locked operation on acquiring the vector without a need for a locked operation to release it.
