Commit Message

Igor Russkikh June 26, 2020, 6:40 p.m. UTC 
A1 requires additional processing for both egress and ingress to support
PTP.
And it makes sense to get rid of this processing altogether (via ifdef),
if PTP clock is disabled globally.

This patch puts the PTP code under the corresponding IS_REACHABLE check.
