385153aa98 Convert the PHY drivers to honor the mii_flags passed down and convert
the NIC drivers as well as the PHY drivers to take advantage of the
mii_attach() introduced in r213878 to get rid of certain hacks. For
the most part these were:
- Artificially limiting miibus_{read,write}reg methods to certain PHY
  addresses; we now let mii_attach() only probe the PHY at the desired
  address(es) instead.
- PHY drivers setting MIIF_* flags based on the NIC driver they hang
  off from, partly even based on grabbing and using the softc of the
  parent; we now pass these flags down from the NIC to the PHY drivers
  via mii_attach(). This got us rid of all such hacks except those of
  brgphy() in combination with bce(4) and bge(4), which is way beyond
  what can be expressed with simple flags.

While at it, I took the opportunity to change the NIC drivers to pass
up the error returned by mii_attach() (previously by mii_phy_probe())
and unify the error message used in this case where and as appropriate
as mii_attach() actually can fail for a number of reasons, not just
because of no PHY(s) being present at the expected address(es).

9396bcb9a7 nlge (alternate XLR GMAC driver) updates:
- Updates for the message ring clean up in r212321.
- Instead of dropping Tx packet on credit fail, retry send until it
  succeeds.
- Fix freeing mbufs in case of P2P descriptors:
  We cannot free the mbuf when the P2P descriptor freeback is received. The
  mbuf may be still in use by the GMAC, since the P2P freeback indicates that
  it read the P2D descriptors in the P2P message.
  Now we free just the P2P descriptor when the P2P freeback message is
  received.  Another freeback P2D message has been added to the end of
  the packet descriptors, the mbuf will be freed only when we received
  this.

The P2P descriptor issue was reported by srgorti at netlogicmicro dot com.

26d5f66d94 Clean up fast message ring code for XLR.
Fix message ring send path:
- define msgrng_access_enable() which disables local interrupts
  and enables message ring access. Also define msgrng_restore() which
  restores interrupts
- remove all other msgrng enable/disable macros, no need of critical_enter
  and other locking here.
- message_send() fixup: re-read status until pending bit clears
- message_send_retry() fixup: retry only few times with interrupts disabled
- Fix up message_send/message_send_retry callers - call
  msgrng_access_enable() and msgrng_restore() correctly so that interrupts
  are not disabled for long.
- removed unused and obsolete code from sys/mips/rmi/msgring.h
- some style fixes - more later

rge.c (XLR GMAC driver):
- updated for the message ring changes
- remove unused message_send_block()
- retry on credit failure, this is not a permanent failure when credits
  are configured correctly. Add panic if credits are not available to
  send for a long time.

1137e0153e PCIe updates for XLS.
Fix interrupt routing so that the irq returned is correct for XLR and
XLS. This also updates the MSI hack we had earlier - we still don't
really support MSI, but we support some drivers that use MSI, by providing
support for allocating one MSI per pci link - this MSI is directly
mapped to the link IRQ.

44b2b99c10 Revamp XLR interrupt handling, the previous scheme does not work well on
SMP.

We used to route all PIC based interrupts to cpu 0, and used the per-CPU
interrupt mask to enable/disable interrupts. But the interrupt threads can
run on any cpu on SMP, and the interrupt thread will re-enable the interrupts
on the CPU it runs on when it is done, and not on cpu0 where the PIC will
still send interrupts to.

The fix is move the disable/enable for PIC based interrupts to PIC, we will
ack on PIC only when the interrupt thread is done, and we do not use the
per-CPU interrupt mask.

The changes also introduce a way for subsystems to add a function that
will be called to clear the interrupt on the subsystem. Currently This is
used by the PCI/PCIe for doing additional work during the interrupt
handling.
