* if_dwc: fix reinitialization with changed MACJiahao LI2022-09-161-5/+6
| | | | | | | | | | | | It was observed that on RockPro64 hardware, the dwc interface is unable to receive packets after being assigned a new MAC address. The fix is simply to call mii_mediachg() before touching any device registers in dwc_init_locked(). This is consistent with what the OpenBSD driver does.

* if_dwc: avoid duplicate packet countsMitchell Horne2022-07-041-12/+0
| | | | | | | | | | | | | | | | | | | We already increment the unicast IPACKETS and OPACKETS counters in the rx/tx paths, respectively. Multicast packets are counted in the generic ethernet code. Therefore, we shouldn't increment these counters in dwc_harvest_stats(). Drop the early return from dwc_rxfinish_one() so that we still count received packets with e.g. a checksum error.
