bnxt_re/lib: increment psn in case of 0 length packets
|
|
|
|
If application posts a 0 length packet, post send routine
|
|
is skipping to increment the psn number. This will cause
|
|
PSN number to go out of sync and eventually connection would
|
|
terminate due to sequence error.
|
|
|
|
post_send routine must increment the psn number by 1 even
|
|
for zero length packets.
