The patch below implements the Microsoft Point-to-Point Encryption method
as a PPP compressor/decompressor. This is necessary for Linux clients and
servers to interoperate with Microsoft Point-to-Point Tunneling Protocol
(PPTP) servers (either Microsoft PPTP servers or the poptop project) which
use MPPE to encrypt data when creating a VPN.
This patch differs from the kernel_ppp_mppe DKMS pacakge at
pptpclient.sourceforge.net by utilizing the kernel crypto routines rather
than providing its own SHA1 and arcfour implementations.
Minor changes to ppp_generic.c try to prevent a link from disabling
compression (in our case, the encryption) after it has started using
compression (encryption).

This patch kills include/linux/eeprom.h .
Rationale:
- it was only used by one single driver
- even this driver didn't do anything useful with it
- most of this file are non-inline and non-static functions (sic)
This removes include/linux/eeprom.h and cleans drivers/net/ns83820.c up.
If you think eeprom.h should be used more extensively, please consider:
- the code has to be moved from the header file to a .c file
- the currently empty write function has to be implemented
- ns83820.c or any other driver should actually use it

Refine bnx2_poll() logic to write back the most up-to-date status tag
when all work has been processed. This eliminates some occasional
extra interrupts when a older status tag is written even though all
work has been processed.
The idea is to read the status tag just before exiting bnx2_poll() and
then check again for any new work. If no new work is pending, the
status tag written back will not generate any extra interrupt. This
logic is similar to the changes David Miller did to tg3_poll().

This patch is a better fix for Allied Telesyn 2700/2701 FX boards than
the change made in early January this year. It allows the user to
select the speed/duplex via module_param, but if no selection is made,
forces the speed to 100 FD. It fixes both Bugzilla bugs 2669 and 4551.
Tested ia32 and ppc64 by myself, and by the originator of bug 2669.

Display the name eth%d or pci_name() of device which fails to allocate
memory. When changing ring size via ethtool, it also releases the
lock before returning on error. Added comment that the caller of
pcnet32_alloc_ring must call pcnet32_free_ring on error, to avoid leak.

Hi,
This patch provides dynamic two buffer-mode and 3 buffer-mode options.
Previously 2 buffer-mode was compilation option. Now with this patch applied
one can load driver in 2 buffer-mode with module-load parameter
ie.
#insmod s2io.ko rx_ring_mode=2
This patch also provides 3 buffer-mode which provides header separation
functionality. In 3 buffer-mode skb->data will have L2/L3/L4 headers and
"skb_shinfo(skb)->frag_list->data" will have have L4 payload.
one can load driver in 3 buffer-mode with same above module-load parameter
ie.
#insmod s2io.ko rx_ring_mode=3
Please review the patch.

The latest kernel added a pretty ugly fix for the orinoco etherleak bug
which contains bogus skb->len checks already done by the caller and causes
copies of all odd sized frames (which are quite common)
While the skb->len check should be ripped out the other fix is harder to do
properly so I'm proposing for this the -mm tree only until next 2.6.x so
that it gets tested.
Instead of copying buffers around blindly this code implements a padding
aware version of the hermes buffer writing function which does padding as
the buffer is loaded and thus more cleanly and without bogus 1.5K copies.

1) Forgotten counter incrementation in sis900_rx() in case
it doesn't get memory for skb, that leads to whole interface failure.
Problem is accompanied with messages:
eth0: Memory squeeze,deferring packet.
eth0: NULL pointer encountered in Rx ring, skipping
2) If counter cur_rx overflows and there'll be temporary memory problems
buffer can't be recreated later, when memory IS available.
3) Limit the work in handler to prevent the endless packets processing
if new packets are generated faster then handled.

This patch replaces current PowerPC 4xx EMAC driver with
new, re-written from the scratch version. This patch is quite big
(~234K) because there is virtualy 0% of common code between old and
new version.
New driver uses NAPI, it solves stability problems under heavy packet
load and low memory, corrects chip register access and fixes numerous
small bugs I don't even remember now.
This patch has been tested on all supported in 2.6 PPC 4xx boards.
It's been used in production for almost a year now on custom
4xx hardware. PPC32 specific parts are already upstream.
Patch was acked by the current EMAC driver maintainer (Matt Porter). I
will be maintaining this new version.

This patch changes the way the ibmveth driver handles the receive
buffers. The old code mallocs and maps all the buffers in the pools
regardless of MTU size and it also limits the number of buffer pools to
three. This patch makes the driver malloc and map the buffers necessary
to support the current MTU. It also changes the hardcoded names of the
buffer pool number, size, and elements to arrays to make it easier to
change (with the hope of making them runtime parameters in the future).
