Using power of 2 descriptors number makes the ring management easier
and allows to use mask operation instead of wraparound conditions.
Adjust Tx descriptor number to be power of 2 and change calculation to

The previuse code took a send queue entry size for stamping from the
send queue entry pointed by completion queue entry; This 2 reads were
done per packet in completion stage.
The completion burst packets number is managed by fixed size stored in
Tx queue, so we can infer that each valid completion entry actually frees
the next fixed number packets.
The descriptors ring holds the send queue entry, so we just can infer
all the completion burst packet entries size by simple calculation and
prevent calculations per packet.
Adjust completion functions to free full completion bursts packets
by one time and prevent per packet work queue entry reads and
calculations.
Save only start of completion burst or Tx burst send queue entry
pointers in the appropriate descriptor element.

The Tx queue send ring was managed by Tx block head,tail,count and mask
management variables which were used for managing the send queue remain
space and next places of empty or completed work queue entries.
This method suffered from an actual addresses recalculation per packet,
an unnecessary Tx block based calculations and an expensive dual
management of Tx rings.
Move send queue ring calculation to be based on actual addresses while
managing it by descriptors ring indexes.
Add new work queue entry pointer to the descriptor element to hold the
appropriate entry in the send queue.

mlx4 Tx block can handle up to 4 data segments or control segment + up
to 3 data segments. The first data segment in each not first Tx block
must validate Tx queue wraparound and must use IO memory barrier before
writing the byte count.
The previous multi-segment code used "for" loop to iterate over all
packet segments and separated first Tx block data case by "if"
statements.
Use switch case and unconditional branches instead of "for" loop can
optimize the case and prevents the unnecessary checks for each data
segment; This hints to compiler to create optimized jump table.
Optimize this case by switch case and unconditional branches usage.

Proper defines are auto generated by ./configure script based on

Until now, UDP RSS support could not be relied on due to a problem in the
Linux kernel implementation and mlx4 RSS capabilities were not reported at

patches already upstream) and likely backported afterward, UDP RSS support
can be enabled by probing RSS capabilities.
