>Description:
The pause frame selection bits, being set in the transmit configuration word, are reserved (bits 10 & 11).  The proper bits are 7 & 8 for pause frame selection.
>How-To-Repeat:
Pause frame use is never autonegotiated properly.
>Fix:
I added two new defines for the TXCW register (0x178):
diff <NetBSD-current> if_wmreg.h
461a462,463
> #define TXCW_ANE_SYM_PAUSE (1U << 7)
> #define TXCW_ANE_ASYM_PAUSE (1U << 8)

Change the source to use the correct definitions:
diff <NetBSD-current> if_wm.c
3411c3411
<               sc->sc_txcw |= ANAR_X_PAUSE_SYM | ANAR_X_PAUSE_ASYM;
---
>               sc->sc_txcw |= TXCW_ANE_SYM_PAUSE | TXCW_ANE_ASYM_PAUSE;
