Therefore pull out the needed information into a sub-struct

The BIC TCP cwnd problem as identified by Yee-Ting Li and Doug Leith
is that the computation is recalc_ssthresh is incorrect and
BICTCP_1_OVER_BETA/2 should be BICTCP_1_OVER_BETA*2.

My fix is to implement the code from BIC TCP 1.1 which uses a sysctl
to set the beta.  There are a few variable name changes from the 1.1
code, and made the scaling factor a #define instead of hardcoded.

I validated this using netem and kprobes, for more details see

This is a minor modification to the previous patch submission that does
not assume the default contents of the DSPCFG register are zero.

When used with Revision D of the DP83815, the "Recommended Registers
Configuration" from page 78 of the DP83815 data sheet is not entirely
compatible with the driver's "short cable patch".  When the DSPCFG
register is written with the value suggested in the document, then
do_cable_magic() can't read the DSP coefficient and determines that all
cables attached to the DP83815D are 'short', regardless of actual
length.  Short cables (< 30m) cause do_cable_magic to enable additional
attenuation to reduce CRC and idle errors.  If the extra attenuation is
unintentionally enabled for long cables (> 50m?), they will not operate
properly.  The National Semiconductor driver, 'dp83815.c' from
http://www.national.com/appinfo/networks/files/linux_2_4.tar.gz was used
as a basis for this modification.

This makes for better messages on what is going on. It also
allows us (if we want to), to pick the PCI starting address
somewhere else in the gap. That may be a good idea (ie do a

	pci_mem_start = (gapstart + (gapsize >> 3) + 0xfffff) & ~0xfffff;

or similar.

We really don't care about anything beyond the 4GB mark,
so make the tests for that explicit (and add a comment),
and use regular "unsigned long" for the gap information.

Patch from Lennert Buytenhek

This is an old patch from 2.6.9-rc3-ds2 that never made it upstream.
The IXP2000 slowport has two modes of operation, 8-bit and 32-bit.
The slowport itself is a byte-wide bus, and in 8-bit mode, it does the
more-or-less obvious thing: every word read causes four byte reads,
and those bytes are then combined into a word according to the xscale
core's current endian setting.  So, what value you get depends on what
endianity your IXP2000 is running in.
In 32-bit mode, however, it is the slowport itself which combines
bytes into words, and for this it unconditionally uses little endian
mode.  In this mode, word reads from the slowport will return the
same value no matter whether the xscale core is running in big or
little endian mode.  This can be a plus in some cases.  Byte (and
halfword) accesses in 32-bit mode have rather useless semantics
due to this, though.
The usefulness of 32-bit mode is limited to the initial boot.  When
the IXP2000 resets, the slowport is always in 32-bit mode, so if you
flash the bootloader into flash (which is connected to the slowport)
using little-endian byte ordering, the xscale will always read the
instruction stream correctly, no matter whether it's running in big
or little endian mode.
After booting it makes no sense to use 32-bit mode anymore.  Especially
since the slowport's word ordering in 32-bit mode is little endian,
and the IXP2000 is conventionally run in big endian, which gives all
kinds of fun issues when trying to access peripherals connected to
the slowport.
In fact, the current MTD map driver for IXP2000 already sets the
slowport to 8-bit mode because it cannot access the flash otherwise.
However, this means that if the MTD map driver is not compiled in for
some reason, the slowport will stay in 32-bit mode after the initial
boot, which will cause peripheral accesses to unexpectedly break!
