From: Wei Fang <wei.fang@nxp.com> Since a PCI FLR (Function Level Reset) is performed during probe, and the hardware enables VLAN promiscuous mode for all SIs by default after reset, there is no need to explicitly set it in enetc_configure_port(). Remove the redundant initialization of vlan_promisc_simap and the call to enetc_set_vlan_promisc() from enetc_configure_port(). Remove the enetc_set_vlan_promisc(), enetc_enable_si_vlan_promisc() and enetc_disable_si_vlan_promisc() functions, and introduce a new unified function enetc_set_si_vlan_promisc() to enable or disable VLAN promiscuous mode for a specific SI. This simplifies the logic and makes the interface more straightforward. As ENETC V4 only changes the address offset of PSIPVMR register compared to V1 without any functional difference, enetc_set_si_vlan_promisc() can be moved to enetc_pf_common.c in the future with minor adjustments to be reused by the ENETC V4 driver Signed-off-by: Wei Fang <wei.fang@nxp.com> --- .../net/ethernet/freescale/enetc/enetc_hw.h | 5 ++- .../net/ethernet/freescale/enetc/enetc_pf.c | 35 +++++++------------ .../net/ethernet/freescale/enetc/enetc_pf.h | 1 - 3 files changed, 14 insertions(+), 27 deletions(-)
