Subject: dpaa2-switch: keep track of the current learning state per port
X-Git-Tag: accepted/tizen/unified/20230118.172025~7335^2~285^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=62734c7405b749a760c88c3e33d250c9efde263e;p=platform%2Fkernel%2Flinux-rpi.git

dpaa2-switch: keep track of the current learning state per port

Keep track of the current learning state per port so that we can
reference it in the next patches when setting up a STP state.
