Michael Brown 844828cb15 [DHCP] Fix RFC4390 client identifier constructions. 
RFC 4390 provides for the DHCP client identifier to contain the link-layer
hardware type and MAC address when the MAC address exceeds 16 bytes.
However, the hardware type field is only 8 bits; we were assuming 16 bits.

Michael Brown 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.

Michael Brown 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.

Michael Brown 563955ce37 [Infiniband] Add missing list_del()s in ib_create_qp() failure path. 2008-02-23 10:48:10 +00:00
Michael Brown 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).

Michael Brown f6a8158eed Make seek information part of the xfer metadata, rather than an entirely 
separate xfer method.

Add missing .alloc_iob entries to several xfer_interface_operations
structures.

Michael Brown 3311169707 When the DHCP file/sname fields are empty, don't allow them to override 
their equivalent DHCP-option-specified values.

Michael Brown 798f7f6b8e Kill off some warnings-problematic debug statements in ndp.c; the code 
is non-functional anyway.

Michael Brown f770744ee0 Quick hack to be able to accept transfers from servers that don't 
supply options.
 2007-11-25 16:06:29 +00:00
Michael Brown b3abf25e3c Allow DHCP server to instruct gPXE to ignore ProxyDHCP (which will 
also avoid waiting for ProxyDHCP offers).

Also reduce the ProxyDHCP timeout, because it's already irritating me.
 2007-11-21 22:10:04 +00:00
Michael Brown 0becbf5fba Add ProxyDHCP support. 2007-11-21 21:51:43 +00:00
Michael Brown fb809da2df Remove some assumptions about DHCP obtaining only a single options block. 2007-11-21 04:48:18 +00:00

Michael Brown 26f3a09ccf Add UUID to DHCP request as option 97 (if available). 2007-11-21 03:29:53 +00:00
Michael Brown 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.

Michael Brown 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.
 2007-10-04 14:46:56 +01:00
Michael Brown 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.

Michael Brown 387a1a8556 Minor debug message improvement. 2007-09-17 18:57:32 +01:00

Michael Brown 251cc84ed6 Started implementing create_qp() and destroy_qp(). 2007-09-16 19:03:24 +01:00
Michael Brown b21d4ca21e Revert to dev_priv/owner_priv scheme, rather than container_of; it 
makes it easier to put the generic allocation code into infiniband.c
 2007-09-16 17:25:15 +01:00
Michael Brown 37fc40bc8c post_recv() now works, and we can pass data on the IPoIB queue pair 
using entirely our own code.

Michael Brown 8deef093d9 Direct polling of TX completion queue now works. 2007-09-15 20:58:29 +01:00
Michael Brown 08e8dfd801 Now handling TX completions in our poll loop. 2007-09-14 11:10:25 +01:00
Michael Brown 30a19c3f1c Can now both send and receive packets. LL header format not yet 
fixed; still using a quick hack-up just to be able to pass through
data.
 2007-09-13 14:43:12 +01:00
Michael Brown 7e4e5af462 Use RFC4390 whenever hardware address exceeds 16 bytes; this allows us 
to construct DHCP packets suitable for Infiniband.

Michael Brown 00d93c6dd9 Minor style fix: structure fields are generally initialised in the 
order in which they occur.

Michael Brown 2ff1b1245b Use start_timer_nodelay() in protocols which rely on the retry timer 
to generate the initial transmission; this cuts off around 0.3s per
instantiated connection.

Michael Brown 0a3c2b80ea Add start_timer_nodelay() 2007-08-13 10:59:00 -07:00
Michael Brown 9fd6a0418f Allowed zero-cost enforced ordering of features in startup banner

and generate DHCP options to indicate features to DHCP server (and to
PXE NBPs).
