From 43c670c8e48a1817ae4b64683d7d65cad5bb0502 Mon Sep 17 00:00:00 2001 From: Igor Russkikh Date: Thu, 30 Apr 2020 11:04:45 +0300 Subject: net: atlantic: A2 ingress / egress hw configuration Chip generations are mostly compatible register-wise, but there are still some differences. Therefore we've made some of first generation (A1) code non-static to re-use it where possible. Some pieces are A2 specific, in which case we redefine/extend such APIs.
