[autoboot] Ensure that an error message is always printed for a boot failure
The case of an unsupported SAN protocol will currently not result in
any error message. Fix by printing the error message at the top level
using strerror(), rather than using hard-coded error messages in the
error paths.
[susieq] Update qib_genbits.pl to handle SusieQ definitions
The latest RTL-generated register lists include (mostly redundant)
xxx_MSB values alongside xxx_LSB and xxx_RMASK, and also include
default register values.
Some subnet managers expect the GetResponse from a SetPortInfo MAD to
contain the new link state. The transition is not immediate, so we
often end up returning the previous link state. This can cause the SM
to fail to activate the port.
Fix by waiting for up to 20us for the link state transition to take
effect.
[ipoib] Mask out non-QPN bits in the IPoIB destination MAC when sending
The first byte of the IPoIB MAC address is used for flags indicating
support for "connected mode". Strip out the non-QPN bits of the first
dword when constructing the address vector for transmitted IPoIB
packets, so as not to end up passing an invalid QPN in the BTH.
[infiniband] Make node description invariant across all ports
IBA section 14.2.5.2 states that "the contents of the NodeDescription
attribute are the same for all ports on a node". Satisfy this by
using the HCA GUID rather than the port GUID to form the node
description string.
[ipv4] Ignore non-open net devices when performing routing
We do not discard routing table entries when closing an interface. It
is plausible that multiple interfaces may be on the same physical
network; if so, then we may end up in a situation whereby outbound
packets attempt to route via a closed interface.
Fix by ignoring non-open net devices in ipv4_route().
ipv4.c calculates the default subnet mask before calling
fetch_ipv4_setting() to retrieve the configured subnet mask (if any).
However, as of commit 612f4e7 "[settings] Avoid returning
uninitialised data on error in fetch_xxx_setting()",
fetch_ipv4_setting() will zero the IP address if the setting does not
exist, rather than leaving it unaltered.
Fix by fetching the setting first and calculating the default subnet
mask only if necessary.
[ipv4] Use a zero address to indicate "no gateway", rather than INADDR_NONE
ipv4.c uses a gateway address of INADDR_NONE to represent "no
gateway". It initialises the gateway address to INADDR_NONE before
calling fetch_ipv4_setting() to retrieve the configured gateway
address (if any).
However, as of commit 612f4e7 "[settings] Avoid returning
uninitialised data on error in fetch_xxx_setting()",
fetch_ipv4_setting() will zero the IP address if the setting does not
exist, rather than leaving it unaltered.
Fix by using a zero IP address to indicate "no gateway", so that a
non-existent gateway address setting will be treated as such.
The PXE type field is canonically little-endian, but the pxebs command
treats it as big-endian in converting the type number passed on the
command line to a field value to search against. Fix, to prevent the
necessity of incantations like "pxebs net0 1536" to select menu item #6.

[netdevice] Add the concept of an "Ethernet-compatible" MAC address
The iBFT is Ethernet-centric in providing only six bytes for a MAC
address. This is most probably an indirect consequence of a similar
design flaw in the Windows NDIS stack. (The WinOF IPoIB stack
performs all sorts of contortions in order to pretend to the NDIS
layer that it is dealing with six-byte MAC addresses.)
There is no sensible way in which to extend the iBFT without breaking
compatibility with programs that expect to parse it. Add the notion
of an "Ethernet-compatible" MAC address to our link layer abstraction,
so that link layers can provide their own workarounds for this
limitation.

[ath5k] Save proper cacheline size when fixing PCI configuration
Some BIOSes set the PCI cacheline size to zero for the card; the ath5k
driver fixes it to a reasonable in PCI config space, but failed to
correct the internal value it had already read. This resulted in
divide-by-zero errors when cacheline-aligning various data structures.
Fix by setting the internal cachelsz to a sane value at the same time
as we write that value to PCI config space.

- Examining the Linux 2.6.30-rc4 igb driver, which supports this card and;
- Information available in the Intel® 82576 Gigabit Ethernet
Controller Datasheet v2.1, which is available from Intel's web site.
I only have a dual-ported card with Copper PHY, so any code paths relating
to Fibre haven't been tested. Also, I have only tested using auto-negotiation
of speed and duplex, and no flow control. Other code paths relating to
those settings also have not been exercised.

A jump instruction starts at the third byte of an option ROM image, and
it is required that the bytes in the whole image add up to zero. To
achieve this, a checksum byte is usually placed after the jump. The jump
can be either a short jump (2 bytes, EB xx) or a near jump (3 bytes,
E9 xx xx). gPXE's romprefix.S uses a near jump, but modrom.pl assumed
a short jump, and clobbered the high byte of the offset. This caused
modrom-modified gPXE ROM images to crash the system during POST.
Fix by making modrom.pl place the checksum at byte 6, like makerom.pl does.

[802.11] Properly initialize autoassociation process
The recent change to process_add() to detect duplicate process
additions relies on the fact that all processes will be initialized
using process_init_stopped() before being passed to that function.
The autoassociation process was not initialized in this fashion, so
process_add() erroneously detected it as a duplicate.
Fix by using process_init_stopped() to initialize the autoassociation
process instead of setting the step member directly.
