Venkat Duvvuru c1bb0a5588 be2net: don't enable multicast flag in be_enable_if_filters() routine ... When the interface is opened (in be_open()) the routine be_enable_if_filters() must be called to switch on the basic filtering capabilities of an interface that are not changed at run-time. These include the flags UNTAGGED, BROADCAST and PASS_L3L4_ERRORS. Other flags such as MULTICAST and PROMISC must be enabled later by be_set_rx_mode() based on the state in the netdev/adapter struct. be_enable_if_filters() routine is wrongly trying to enable MULTICAST flag without checking the current adapter state. This can cause the RX_FILTER cmds to the FW to fail. This patch fixes this problem by only enabling the basic filtering flags in be_enable_if_filters(). The VF must be able to issue RX_FILTER cmd with any filter flag, as long as the PF allowed those flags (if_cap_flags) in the iface it provisioned for the VF. This rule is applicable even when the VF doesn't have the FILTMGMT privilege. There is a bug in BE3 FW that wrongly fails RX_FILTER multicast programming cmds on VFs that don't have FILTMGMT privilege. This patch also helps in insulating the VF driver from be_open failures due to the FW bug. A fix for the BE3 FW issue will be available in versions >= 11.0.283.0 and 10.6.334.0 Reported-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: Venkat Duvvuru <venkatkumar.duvvuru@avagotech.com> Signed-off-by: Sathya Perla <sathya.perla@broadcom.com> Signed-off-by: David S.
