net: hibmcge: fix incorrect pause frame statistics issue
The driver supports pause frames,
but does not pass pause frames based on rx pause enable configuration,
resulting in incorrect pause frame statistics.
like this:
mz eno3 '01 80 c2 00 00 01 00 18 2d 04 00 9c 88 08 00 01 ff ff' \
-p 64 -c 100
ethtool -S enp132s0f2 | grep -v ": 0"
NIC statistics:
rx_octets_total_filt_cnt: 6800
rx_filt_pkt_cnt: 100
The rx pause frames are filtered by the MAC hardware.
This patch configures pass pause frames based on the
rx puase enable status to ensure that
rx pause frames are not filtered.
mz eno3 '01 80 c2 00 00 01 00 18 2d 04 00 9c 88 08 00 01 ff ff' \
-p 64 -c 100
ethtool --include-statistics -a enp132s0f2
Pause parameters for enp132s0f2:
Autonegotiate: on
RX: on
TX: on
RX negotiated: on
TX negotiated: on
Statistics:
tx_pause_frames: 0
rx_pause_frames: 100
