net: enetc: extract common helpers for MAC hash filter configuration

Browse source

The PSIUMHFR and PSIMMHFR registers in ENETC v4 have the same bit layout
as in ENETC v1. The only difference between the two hardware generations
is the register address offsets.

Since the register functionality is identical, the MAC hash filter
configuration code can be shared between the ENETC v1 and v4 drivers.
Extract two new common helper functions, enetc_set_si_uc_hash_filter()
and enetc_set_si_mc_hash_filter(), into enetc_pf_common.c. These helpers
select the correct register offset based on the hardware revision via
is_enetc_rev1().

Remove v1-specific enetc_clear_mac_ht_flt() and enetc_set_mac_ht_flt()
from enetc_pf.c, and v4-specific enetc4_pf_set_si_uc_hash_filter() and
enetc4_pf_set_si_mc_hash_filter() from enetc4_pf.c, as they are now
superseded by the shared implementations.
