[PATCH v2 2/8] net/bonding: skip unavailable member stats

[Stephen Hemminger <stephen@networkplumber.org>]

From: Weijun Pan <wpan3636@gmail.com>

bond_ethdev_stats_get() accumulates statistics from each bonding
member. If rte_eth_stats_get() fails for a member, the local
member_stats structure may be left unchanged.

Skip members whose statistics cannot be read, instead of accumulating
stale or uninitialized counters.

Fixes: 2efb58cbab6e ("bond: new link bonding library")
