Subject: RDMA/irdma: Use s/g array in post send only when its valid
From: Sindhu-Devale <sindhu.devale@xxxxxxxxx>
commit 2c8844431d065ae15a6b442f5769b60aeaaa07af upstream.
Send with invalidate verb call can pass in an
uninitialized s/g array with 0 sge's which is
filled into irdma WQE and causes a HW asynchronous
event.
Fix this by using the s/g array in irdma post send
only when its valid.
