Subject: bonding: feature arc may not be enabled for the slave interface
X-Git-Tag: v20.05-rc0~646
X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F34%2F22634%2F3;hp=c31dc31f84961033ecb6354811e0c360b6cf5f79;p=vpp.git

bonding: feature arc may not be enabled for the slave interface

vnet_feature_enable_disable takes sw_if_index, not hw_if_index. If there
is a subinterface created prior to the slave interface is created,
sw_if_index and hw_if_index start to diverge and the problem will happen.

Type: fix
