Subject: net: dsa: bcm_sf2: Utilize b53_get_tag_protocol()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9f66816a6a4dd740bfa29cc8a8e19b90fd7df4e7;p=openwrt%2Fstaging%2Fblogic.git

net: dsa: bcm_sf2: Utilize b53_get_tag_protocol()

Utilize the much more capable b53_get_tag_protocol() which takes care of
all Broadcom switches specifics to resolve which port can have Broadcom
tags enabled or not.
