[PATCH 5.10 178/221] RDMA/cxgb4: Fix adapter LE hash errors while destroying ipv6 listening server

From: Greg Kroah-Hartman
Date: Mon Mar 29 2021 - 04:43:51 EST


From: Potnuri Bharat Teja <bharat@xxxxxxxxxxx>

[ Upstream commit 3408be145a5d6418ff955fe5badde652be90e700 ]

Not setting the ipv6 bit while destroying ipv6 listening servers may
result in potential fatal adapter errors due to lookup engine memory hash
errors. Therefore always set ipv6 field while destroying ipv6 listening
servers.

Fixes: 830662f6f032 ("RDMA/cxgb4: Add support for active and passive open connection with IPv6 address")
