[dpdk-dev] [PATCH v2] net/qede: fix unknown speed errmsg for 25G link

Fri Nov 11 18:41:36 CET 2016


- Fix to use bitmapped values in NVM configuration for speed capability
  advertisement. This issue is specific to 25G NIC since it is capable
  of 25G and 10G speeds.

- Update feature list.

Fixes: 64c239b7f8b7 ("net/qede: fix advertising link speed capability")
