d6bdd318a3 Assorted fixes for mge(4).
- Use proper map for the busdma sync on mge descriptor.
- Remove unnecesary busdma sync.
- Eliminate redundant locking in mge_reinit_rx() (just assert).
- Kill unused variable.

18159f6a49 Introduce MII_ADDR_BASE option on ARM, which allows to override the default
per platform requirements.

Notes:
- Only used by mge(4) at the moment.

- This is very simplified approach and should be replaced by some long-term
  solution for managing the board/platform configuration (among others the
  MAC-PHY binding info).

eb956cd041 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

1abcdbd127 When user_frac in the polling subsystem is low it is going to busy the
CPU for too long period than necessary.  Additively, interfaces are kept
polled (in the tick) even if no more packets are available.
In order to avoid such situations a new generic mechanism can be
implemented in proactive way, keeping track of the time spent on any
packet and fragmenting the time for any tick, stopping the processing
as soon as possible.

In order to implement such mechanism, the polling handler needs to
change, returning the number of packets processed.
While the intended logic is not part of this patch, the polling KPI is
broken by this commit, adding an int return value and the new flag
IFCAP_POLLING_NOCOUNT (which will signal that the return value is
meaningless for the installed handler and checking should be skipped).

Bump __FreeBSD_version in order to signal such situation.

5817716faf mge(4): fix two bugs, which were leading to crash/hang under very heavy
network load.

1. Leave the RX interrupt routine if there is no mbuf available.

2. Properly initialize and track tx_desc_used_count counter so as not to
leak mbuf while traversing used descriptors.

8e1dc58e8c Handle mge(4) chip revision differences at run-time rather then compile time,
which is more flexible for future revisions, and lets eliminate some #defines
and compile conditionals.

9f55f5f5cf Marvell Gigabit Ethernet controller driver.
This supports 1Gbps Ethernet engine found on ARM-based SOCs (Orion, Kirkwood,
Discovery), as well as on system controllers for PowerPC processors (MV64430,
MV6446x).

The following advanced features are supported:

  - multicast
  - VLAN tagging
  - IP/TCP/UDP checksum calculation offloading
  - polling
  - interrupt coalescing
