RDMA/bnxt_re: Fix IB_SEND_IP_CSUM handling in post_send

Browse source

[ Upstream commit f01765a236 ]

The bnxt_re SEND path checks wr->send_flags to enable features such as
IP checksum offload. However, send_flags is a bitmask and may contain
multiple flags (e.g. IB_SEND_SIGNALED | IB_SEND_IP_CSUM), while the
existing code uses a switch() statement that only matches when
send_flags is exactly IB_SEND_IP_CSUM.

As a result, checksum offload is not enabled when additional SEND
flags are present.

Replace the switch() with a bitmask test:

    if (wr->send_flags & IB_SEND_IP_CSUM)

This ensures IP checksum offload is enabled correctly when multiple
SEND flags are used.
