Subject: [PATCH net-next] ravb: Add ESF in RCR for enabling separation filter

From: Masaru Nagai <masaru.nagai.vx@...esas.com>

This patch adds enabling separation filter(ESF) is setting value of B'11.
This setting filter for separating AVB stream frames from non-AVB stream
frames is enabled. Non-matching frames from a stream are processed in
queue 0(best effort). H/W manual recommends B'11 or B'10.
When B'10 is setting, Non-mating frames are discarded.
