Subject: [net-next RFC PATCH 06/13] net: hsr: some renaming to introduce PRP driver support
This is a preparatory patch to introduce PRP device support.
PRP device is very much similar to HSR in terms of device
creation/removal, packet handling, etc. So this patch rename
the functions that can be reused for PRP with a hsr_prp prefix.
Common definitions and structure types are prefixed as well
per similar reason. Similarly all constants common to HSR and
PRP are prefixed with HSR_PRP. Common code that uses hsr_dev
for function argument is changed to hsr_prp_dev or dev or
ndev depending on the existing usage and context.
