====================
ibmvnic: Performance improvements and other updates
The first three patches utilize a hypervisor call allowing multiple
TX and RX buffer replenishment descriptors to be sent in one operation,
which significantly reduces hypervisor call overhead. The xmit_more
and Byte Queue Limit API's are leveraged to provide this support
for TX descriptors.
The subsequent two patches remove superfluous code and members in
TX completion handling function and TX buffer structure, respectively,
and remove unused routines.
Finally, four patches which ensure that device queue memory is
cache-line aligned, resolving slowdowns observed in PCI traces,
as well as optimize the driver's NAPI polling function and
to RX buffer replenishment are provided by Dwip Banerjee.
This series provides significant performance improvements, allowing
the driver to fully utilize 100Gb NIC's.
