we have some consistent behavior.

To delay packets from a particular TX queue by a particular time, write a value
into the TX Pace table s.t. pace time <= TX Pace Clock Period * (2 ^ pace value)
- the TX pace clock is 1/13 of the system clock, so its period should be 104 or
52 ns depending on whether turbo mode is active.
EFX_TX_PACE_CLOCK_BASE added by me.

It solves locking problem when EFSYS_MEM_ALLOC is called in
the context holding a mutex (not allowed to sleep).
E.g. on interface bring up or multicast addresses addition.

It is one more place missed in the previous fix.
Most likely is was just memory leak on the error handling path since
typically efsys_mem_t is filled in by zeros on allocation.

LoopRotate: When reconstructing loop simplify form don't split edges
from indirectbrs.
Yet another chapter in the endless story. While this looks like we
leave the loop in a non-canonical state this replicates the logic in
LoopSimplify so it doesn't diverge from the canonical form in any way.

This fixes a "Cannot split critical edge from IndirectBrInst" assertion
failure when building the devel/radare2 port.

utilities.
I was originally planning on removing the phase-of-moon (pom), clock
(grdc), and caesar cipher (caesar, rot13) utilities as well, but after
I committed r278616 I received an astonishing volume of email informing
me that those are still being widely used. Much to my relief, nobody
reported continuing to use the punch card utilities in production.
The final step will be to merge src/games into src/usr.bin.
This change will not be MFCed.
Use remaining number of DMA segment instead of maximum number in mapping
when checking space for one more TSO segment packet.

Sync endif comment with conditional.
BOOTROM and SIENA_BOOTROM are the same, but highlight that it is Siena.

a capcity is given, no partitions are required. When no partitions are
given, no scheme needs to be specified either. This makes it possible
to create an entirely empty disk image. To add an empty partitioning
table, specify the scheme.
Bump the version to 20150222.
Drop an unnecessary check in some calculations. The check
would have Coverity falsely conclude that variables could
be left undefined.

follow specification and do not provide PCIe capability.
Verify if the port above such bridge is downstream PCIe (or root port)
and treat the bridge as PCIe/PCI then. This allows to avoid
maintaining the table of device ids for bridges without capability,
while still calculate correct request originator for devices behind
the bridge.

Before the common code had hard coded limits on the IDs RXQs and TXQs could
be created with which were suited for the Windows driver with VMQ, and so
would prevent queues with IDs greater than or equal to 259 (for TXQs) or 768
(for RXQs) from being created. This change allows the limits to be set in
efsys.h, so that all 1024 queues can be created during new manftest tests.
Also, the descriptor cache sizes were also hard coded to values suited to
the smaller queue counts, and so it was necessary to make them configurable
as well.

We must not enable RX queues with random parameters when they are
mapped into a VF with an untrusted driver. It's probably not a good
idea to do this anyway, so take this bit out of the table test masks.
