Tariq Toukan 36154be40a net/mlx5e: Fix wrong CQE decompression ... In cqe compression with striding RQ, the decompression of the CQE field wqe_counter was done with a wrong wraparound value. This caused handling cqes with a wrong pointer to wqe (rx descriptor) and creating SKBs with wrong data, pointing to wrong (and already consumed) strides/pages. The meaning of the CQE field wqe_counter in striding RQ holds the stride index instead of the WQE index. Hence, when decompressing a CQE, wqe_counter should have wrapped-around the number of strides in a single multi-packet WQE. We dropped this wrap-around mask at all in CQE decompression of striding RQ. It is not needed as in such cases the CQE compression session would break because of different value of wqe_id field, starting a new compression session. Tested: ethtool -K ethxx lro off/on ethtool --set-priv-flags ethxx rx_cqe_compress on super_netperf 16 {ipv4,ipv6} -t TCP_STREAM -m 50 -D verified no csum errors and no page refcount issues.
