| Subject: RDMA/cxgb4: Fix adapter LE hash errors while destroying ipv6 |
| listening server |
| |
| From: Potnuri Bharat Teja <bharat@chelsio.com> |
| |
| [ 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") |
