[ Upstream commit ff672b9ffeb3f82135488ac16c5c5eb4b992999b ]
Both ipvlan_process_v4_outbound() and ipvlan_process_v6_outbound()
increment dev->stats.tx_errors in case of errors.
Unfortunately there are two issues :
1) ipvlan_get_stats64() does not propagate dev->stats.tx_errors to user.
2) Increments are not atomic. KCSAN would complain eventually.
Use DEV_STATS_INC() to not miss an update, and change ipvlan_get_stats64()
to copy the value back to user.
Fixes: 2ad7bf363841 ("ipvlan: Initial check-in of the IPVLAN driver.")
