ibmvnic: Unmap DMA address of TX descriptor buffers after use
There's no need to wait until a completion is received to unmap TX descriptor buffers that have been passed to the hypervisor. Instead unmap it when the hypervisor call has completed. This patch avoids the possibility that a buffer will not be unmapped because a TX completion is lost or mishandled. Reported-by:Abdul Haleem <abdhalee@linux.vnet.ibm.com> Tested-by:
