Change Details

Move per-packet counter_enter/counter_exit pairs out of the RX processing loop and batch them into a single update after the loop completes. Previously, each received packet triggered two separate counter_enter/counter_exit critical sections -- one for bytes and one for packet count. This commit accumulates totals in local variables and updates all four counters (ring and hw stats for both packets and bytes) in a single critical section after the loop. Also move the stats update to after the refill and LRO flush so that the error path (goto update_stats) and the normal path converge at the same label, avoiding code duplication.
