There were some errors in the way that internal Gather Lists were being
translated into skb's. This also makes the VF Driver look more like the PF
Driver to facilitate easier comarison.

fresh skbs have ip_summed set to CHECKSUM_NONE (0)
We can avoid setting again skb->ip_summed to CHECKSUM_NONE in drivers.
Introduce skb_checksum_none_assert() helper so that we keep this
assertion documented in driver sources.
Change most occurrences of :
skb->ip_summed = CHECKSUM_NONE;
by :
skb_checksum_none_assert(skb);

Fix up TX Queue Host Flow Control to cause an Egress Queue Status Update to
be generated when we run out of TX Queue Descriptors. This will, in turn,
allow us to restart a stopped TX Queue.

We could use DEFINE_DMA_UNMAP_ADDR instead but using
CONFIG_NEED_DMA_MAP_STATE is a simpler way to see if a platform does
real DMA unmapping.

Use correct shift factor for extracting the SGE DMA Ingress Padding
Boundary. Was accidentally using the register field's shift which was
close enough (4 instead of the propper value of 5) that it actually
sort of worked for various packet sizes ...
