sys/dev/bnxt/bnxt_hwrm.c
953 ↗	(On Diff #33211)	Possibly this function should be renamed or split? The implication of bnxt_hwrm_func_cfg() is that it calls HWRM_FUNC_CFG. Maybe bnxt_cfg_async_cr()? Or split into bnxt_hwrm_func_cfg() and bnxt_hwrm_func_vf_cfg() and have the caller choose the correct function?

953 ↗	(On Diff #33211)	OK. Will modify it as bnxt_cfg_async_cr().

Renamed bnxt_hwrm_func_cfg to bnxt_cfg_async_cr as later one is more appropriate.

This revision now requires review to proceed.Sep 19 2017, 9:13 AM

Looks good to me.

Since there's no real way to test this on FreeBSD at the moment ...
