These are not netdev statistics but MAC block counters. Guess it is not clear with the naming here, will fix this. We have a use case where the MAC traffic may be redirected from the associated net dev, so the counters may not be the same.

Same comment as above

Looks like the way we are doing stats are a bit outdated. Thanks for pointing it out. I got a bit of refactoring to do.
+ STAT_BCMASP_MIB_RX("rx_mtu_err", mib.rx.mtue), + STAT_BCMASP_MIB_RX("rx_good_pkts", mib.rx.pok), + STAT_BCMASP_MIB_RX("rx_unicast", mib.rx.uc), + STAT_BCMASP_MIB_RX("rx_ppp", mib.rx.ppp), + STAT_BCMASP_MIB_RX("rx_crc", mib.rx.rcrc),hm, what's the difference between rx_crc and rx_fcs ?
This looks like some debug feature that really has nothing to do with verifying crcs. I will remove it.
Apologies, probably should have done my due diligence with each stats instead of blindly including everything.
Thanks, Justin
