Subject: [PATCH 05/24] net: systemport: Fix software statistics for SYSTEMPORT
 Lite
Git-commit: 50ddfbafcd1e1f95185dfaa4ad794f742b0beaf8
Patch-mainline: v4.13-rc5
References: git-fixes

With SYSTEMPORT Lite we have holes in our statistics layout that make us
skip over the hardware MIB counters, bcm_sysport_get_stats() was not
taking that into account resulting in reporting 0 for all SW-maintained
statistics, fix this by skipping accordingly.
