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.
|
||
|
|
|
||
|
|
Fixes: 3bebdf5 ("rdma-core/irdma: Add user/kernel shared libraries")
