The old rfs_filters_added method for determining the quota could potentially
 allow the NIC to become filled with old filters, which never get tested for
 expiry.  Instead, explicitly make expiry check work depend on the number of
 filters installed, and don't count checking slots without filters in as
 doing work.  This guarantees that each filter will be checked for expiry at
 least once every thirty seconds (assuming the channel to which it belongs is
 NAPI polling actively) regardless of fill level.

The FW_ETH_TX_EO_WR used for sending UDP Segmentation Offload (USO)
requests expects the headers to be part of the descriptor and the
payload to be part of the SGL containing the DMA mapped addresses.
Hence, the DMA address in the first entry of the SGL can start after
the packet headers. Currently, unmap_sgl() tries to unmap from this
wrong offset, instead of the originally mapped DMA address.

So, use existing unmap_skb() instead, which takes originally saved DMA
addresses as input. Update all necessary Tx paths to save the original
DMA addresses, so that unmap_skb() can unmap them properly.

Currently when adding/deleting vlans in ice_vc_process_vlan_msg()
we are calling ice_vsi_manage_vlan_stripping() to enable/disable
when adding and deleting a VLAN respectively. This is wrong
because adding/deleting VLANs has nothing to do with configuring
VLAN stripping. VLAN stripping is configured through the
following VIRTCHNL operations:
	VIRTCHNL_OP_ENABLE_VLAN_STRIPPING
	VIRTCHNL_OP_DISABLE_VLAN_STRIPPING

Unfortunately we can't just remove this because then stripping
will never be configured on VF initialization. Fix this by
adding a new function that initializes (disables/enables) VLAN
stripping for the VF based on the device supported capabilities.
This allows us to remove the call to
ice_vsi_manage_vlan_stripping() in ice_vc_process_vlan_msg().
