From: Vladimir Oltean Date: Mon, 19 Jul 2021 17:14:49 +0000 (+0300) Subject: net: dsa: make tag_8021q operations part of the core X-Git-Tag: accepted/tizen/unified/20230118.172025~6527^2~456^2~3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5da11eb407340233a6111c563419e19685a062a4;p=platform%2Fkernel%2Flinux-rpi.git net: dsa: make tag_8021q operations part of the core Make tag_8021q a more central element of DSA and move the 2 driver specific operations outside of struct dsa_8021q_context (which is supposed to hold dynamic data and not really constant function pointers).
