Subject: bgmac: reset cached MAC state during chip reset
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d469962f858b71ec43112c256e3df4a60b00beeb;p=deliverable%2Flinux.git

bgmac: reset cached MAC state during chip reset

Without this bgmac_adjust_link didn't know it should re-initialize MAC
state. This led to the MAC not working after if down & up routine.
