bc3f0a25c6 [Infiniband] Add preliminary support for multi-port devices. 
Arbel and Hermon cards both have multiple ports.  Add the
infrastructure required to register each port as a separate IB
device.  Don't yet register more than one port, since registration
will currently fail unless a valid link is detected.

Use ib_*_{set,get}_{drv,owner}data wrappers to access driver- and
owner-private data on Infiniband structures.

6570203571 [Infiniband] Centralise MAD operations 
Pull out common code for handling management datagrams from arbel.c
and hermon.c into infiniband.c.

Add port number to struct ib_device.

Add open(), close() and mad() methods to struct ib_device_operations.

428c6342bc Fixes for EqualLogic iSCSI targets: 
Allow port numbers in iSCSI redirection.

  Wait for SCSI status, not just the final data-in (which may be followed
  by an explicit SCSI Response PDU if the S bit is not set).

b3abf25e3c Allow DHCP server to instruct gPXE to ignore ProxyDHCP (which will

c194b0c4bf Work around a bug in the OpenSolaris iSCSI target. 
We didn't specify values for MaxRecvDataSegmentLength and
MaxBurstLength (to save space, since we were happy with the
RFC-defined default values of 8kB and 256kB respectively).  However,
the OpenSolaris target (incorrectly) assumes default values of zero
for these parameters.

The upshot was that the OpenSolaris target would get stuck in an
endless loop trying to send us the first 512-byte sector, zero bytes
at a time, and would eventually run out of memory and core-dump.

Fixed by explicitly specifying the default values for these two
parameters.

2303c45d65 Force a netdevice poll in net_tx() before attempting to transmit 
packet, to work around the problem whereby small TX rings get backed
up because we haven't yet poll()ed for TX completions.

267a4483ab Added an almost obscene amount of debugging and assertion code while 
tracking down a bug that turned out to be a free_iob() used where I
needed a netdev_tx_complete().  This left the freed I/O buffer on the
net device's TX list, with bad, bad consequences later.

Also fixed the bug in question.

ff5aac826a hoffmeis: Fixing situation where absence of a newdata() handler for UDP

520d9c36af Updated ISAPnP, EISA, MCA and ISA buses to current device model. 
ISA 3c509 is currently non-functional, although the EISA (3c509-eisa) and
MCA (3c529) variants should build OK.

None of this code is yet tested.
