net: hns3: keep MAC pause mode when multiple TCs are enabled (d78e5b6a) · Commits · 戴 / test

Bellow HNAE3_DEVICE_VERSION_V3, MAC pause mode just support one TC, when enabled multiple TCs, force enable PFC mode. HNAE3_DEVICE_VERSION_V3 can support MAC pause mode on multiple TCs, so when enable multiple TCs, just keep MAC pause mode, and enable PFC mode just according to the user settings. Signed-off-by:
