Subject: ralink: fix tx vlan offload and hardware status
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e1f6d0dd0ae64b242b73db4d3646d25a059b5ed2;p=openwrt%2Fstaging%2F981213.git

ralink: fix tx vlan offload and hardware status

hardware status and tx vlan offload support on all targets
except rt5350. so i modify the IS_ENABLE condition only for
mt7621.
support mt7621 hardware status reference by SDK. but i don't
have mt7621. if not work just set mt7621 FE_REG_FE_COUNTER_BASE
to 0 to let software count.
