net: prueth: add support of hsr/prp vlan pcp to rx queue map
Usage: in dts/pruss2_eth{} node, add property
pcp-rxq-map = /bits/ 8 <3 3 2 2 1 1 0 0>;
where (from left to right) low-pcp to high-pcp:
pcp rxq
------------------------------
0 3 (q4) low priority
1 3 (q4)
2 2 (q3)
3 2 (q3)
4 1 (q2)
5 1 (q2)
6 0 (q1)
7 0 (q1) high priority
Note 1:
If no pcp-rxq-map is defined, the default is
<3 3 2 2 1 1 0 0>.
Note 2:
If a pcp is mapped to a rx queue (even it is the
default case), it is user's responsibility to make
sure that the rx queue have enough buffers, ie. 48,
to receive at least one regular size frame.
