[ Upstream commit 39797a27 ] The comparison check between cur_hw_state and hw_state is currently invalid because cur_hw_state is right shifted by G_MISTP_SHIFT, while hw_state is not, so we end-up comparing bits 2:0 with bits 7:5, which is going to cause an additional aging to occur. Fix this by not shifting cur_hw_state while reading it, but instead, mask the value with the appropriately shitfted bitmask. The other problem with the fast-ageing process is that we did not set the EN_AGE_DYNAMIC bit to request the ageing to occur for dynamically learned MAC addresses. Finally, write back 0 to the FAST_AGE_CTRL register to avoid leaving spurious bits sets from one operation to the other.
