Subject: net/qede: fix device stop to remove primary MAC
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=83ade1ebdbfc8211d3cb5c2bc282c3fa396e4a34;p=dpdk.git

net/qede: fix device stop to remove primary MAC

This fix is to remove primary MAC filter during dev stop. Without the
fix device start attempt to add the primary MAC fails. Perform MAC set
remove under IS_PF() check.

Fixes: dd28bc8c6ef4 ("net/qede: fix VF port creation sequence")
