Subject: [PATCH 18/18] ethtool: don't fall back to grxfhindir when context was
|
|
|
149f89 |
specified
|
|
|
149f89 |
|
|
|
149f89 |
In do_grfxh(), if rss_context is non-zero, we must not fall back to
|
|
|
149f89 |
do_grxfhindir() if ETHTOOL_GRSSH fails, for that reads the default RSS
|
|
|
149f89 |
context and not the one specified.
|
|
|
149f89 |
|
|
|

Fixes: f5d55b967e0c ("ethtool: add support for extra RSS contexts and RSS steering filters")
