Subject: vlan: Fix build error wth vlan_get_encap_level()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e1618d461ca18d40f9c3ef70598abb72e75d27ae;p=linux-beck.git

vlan: Fix build error wth vlan_get_encap_level()

The new function vlan_get_encap_level() uses vlan_dev_priv()
which is only conditionally avaialble when VLAN support is
enabled.  Make vlan_get_encap_level() conditionally available
as well.

Fixes: 44a4085538c8 ("bonding: Fix stacked device detection in arp monitoring")
