net/nfp: update incorrect MAC stats offset
Checks
Commit Message
From: James Hershaw <james.hershaw@corigine.com>
The pointer to the beginning of the MAC stats counters for port 1 are
incorrectly set as the pointer to the beginning of the port 0 MAC stats
counters, plus the size of the MAC stats counters multiplied by the port
number.
This patch corrects this by setting the multiplier as the eth_table
index of the port.
Fixes: f26e82397f6d ("net/nfp: implement xstats")
