Merge branch 'bcmgenet-Fragmented-SKB-corrections'
Doug Berger says:
====================
bcmgenet: Fragmented SKB corrections
Two issues were observed in a review of the bcmgenet driver support for
fragmented SKBs which are addressed by this patch set.
The first addresses a problem that could occur if the driver is not able
to DMA map a fragment of the SKB. This would be a highly unusual event
but it would leave the hardware descriptors in an invalid state which
should be prevented.
The second is a hazard that could occur if the driver is able to reclaim
the first control block of a fragmented SKB before all of its fragments
have completed processing by the hardware. In this case the SKB could
be freed leading to reuse of memory that is still in use by hardware.
