From 660ac56e1ee71a177554432e9b9994aea1bdd0d4 Mon Sep 17 00:00:00 2001 From: Sindhu-Devale Date: Thu, 8 Sep 2022 17:22:32 -0400 Subject: providers/irdma: Use s/g array in post send only when its valid [ Upstream commit 7bc6e3b49cdac9776e740e9d886e3676524996f8 ] 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.
