net: atlantic: per-TC queue statistics
This patch adds support for per-TC queue statistics. By default (single TC), the output is the same as it used to be, e.g.: Queue[0] InPackets: 2 Queue[0] OutPackets: 8 Queue[0] Restarts: 0 Queue[0] InJumboPackets: 0 Queue[0] InLroPackets: 0 Queue[0] InErrors: 0 If several TCs are enabled, then each queue statistics line is prefixed with TC number, e.g.: TC0 Queue[0] InPackets: 6 TC0 Queue[0] OutPackets: 11 Queue numbering is end-to-end, so: TC1 Queue[4] InPackets: 0 TC1 Queue[4] OutPackets: 22 Signed-off-by: Mark Starovoytov <mstarovoitov@marvell.com> Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S.
