enic: improve Rx performance This is a wholesale replacement of the Enic PMD receive path in order to improve performance and code clarity. The changes are: - Simplify and reduce code path length of receive function. - Put most of the fast-path receive functions in one file. - Reduce the number of posted_index updates (pay attention to rx_free_thresh) - Remove the unneeded container structure around the RQ mbuf ring - Prefetch next Mbuf and descriptors while processing the current one - Use a lookup table for converting CQ flags to mbuf flags.

net/enic: support scattered Rx For performance reasons, this patch uses 2 VIC RQs per RQ presented to DPDK. The VIC requires that each descriptor be marked as either a start of packet (SOP) descriptor or a non-SOP descriptor. A one RQ solution requires skipping descriptors when receiving small packets and results in bad performance when receiving many small packets. The 2 RQ solution makes use of the VIC feature that allows a receive on primary queue to 'spill over' into another queue if the receive is too large to fit in the buffer assigned to the descriptor on the primary queue. This means that there is no skipping of descriptors when receiving small packets and results in much better performance.

net/enic: count truncated packets Truncated packets occur on enic if an mbuf is not big enough to receive it or there aren't enough mbufs if rx scatter is in use. They show up as error packets but unlike other error packets (like packets bad FCS) there are no nic drop counts incremented for them. Truncated packets are calculated by subtracting hardware errors from software errors. Note: this causes transient inaccuracies in the ipackets count. Also, the length of truncated packets are counted in ibytes even though truncated packets are dropped which can make ibytes be slightly higher than it should be.

enic: improve Tx packet rate For every packet sent, a completion was being requested and the posted_index register on the nic was being updated. Instead, request a completion and update the posted index once per burst after all packets have been sent by the burst function.

enic: improve Rx performance This is a wholesale replacement of the Enic PMD receive path in order to improve performance and code clarity. The changes are: - Simplify and reduce code path length of receive function. - Put most of the fast-path receive functions in one file. - Reduce the number of posted_index updates (pay attention to rx_free_thresh) - Remove the unneeded container structure around the RQ mbuf ring - Prefetch next Mbuf and descriptors while processing the current one - Use a lookup table for converting CQ flags to mbuf flags.

net/enic: remove unused functions in Tx path Functions existed which were never called. Removed them. Also rename the 'pmd' from the name of the Tx function to improve clarity. Signed-off-by: John Daley <johndale@cisco.com>
