It seems you're making two different changes in a single commit, you could split it. Updating the SCI according to the new MAC address applies here to both the s/w implementation and the offloaded ones: it looks like this is fixing an issue when the MAC address is updated. If so, could you send it accordingly (as a fix)? Thanks!
