The way the hardware and firmware work is that there is one shared RX
queue and IRQ for a number of different network interfaces. Due to this,
we would like to process received packets for every interface in the same
NAPI poll handler, so we need a pseudo-device to schedule polling on.
What the driver currently does is that it always schedules polling for
the first network interface in the list, and processes packets for every
interface in the poll handler for that first interface -- however, this
scheme breaks down if the first network interface happens to not be up,
since netif_rx_schedule_prep() checks netif_running().
sky2 apparently has the same issue, and Stephen Hemminger suggested a
way to work around this: create a variant of netif_rx_schedule_prep()
that does not check netif_running(). I implemented this locally and
called it netif_rx_schedule_prep_notup(), and it seems to work well,
but it's something that probably not everyone would be happy with.
The ixp2000 is an ARM CPU with a high-speed network interface in the
CPU itself (full duplex 4Gb/s or 10Gb/s depending on the IXP model.)
The CPU package also contains 8 or 16 (again depending on the IXP
model) 'microengines', which are somewhat primitive but very fast
and efficient processor cores which can be used to offload various
things from the main CPU.
This driver makes the high-speed network interface in the CPU visible
and usable as a regular linux network device. Currently, it only
supports the Radisys ENP2611 IXP board, but adding support for other
board types should be fairly easy.

For the four versions of hardware that we (currently) support microcode
download on, the default configuration of our receive interrupt mitigation
microcode was too aggressive, and caused unnecessary delays when pinging,
and low(er) throughput on single connection latency sensitive performance
tests.
This code adds microcode support, and sets the defaults to more reasonable
settings. It also explains the functionality in the code in more detail.
Compile and load tested, shows expected behavior for slight delay of ping
packets (1-2ms) when ucode is loaded, and decent interrupt moderation for
small packets, while maintaining good throughput.

The smc91x driver relies upon register bank 2 being selected whenever
the interrupt handler is called. This isn't always so, especially if
we have a link change event during PHY configuration.
This results in register bank 0 being selected when the interrupt
handler is called, causing the wrong registers to be read for the
IRQ mask and status. In turn, this causes us to spin with a
permanently asserted IRQ.
The patch ensures that smc_phy_configure always exits with register
bank 2 selected.

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).
Feedback to <pptpclient-devel@lists.sourceforge.net> please.

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
Noone did any of these during the more than 3 years eeprom.h already

Because of the frequent channel change, it is possible that when we are

Another channel change comes at this time, then the driver will issue

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 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

fid is declared as a u32 (unsigned int), and then a few lines later, it is checked for a value < 0, which is clearly useless.
In the two locations this function is used, in one it is *explicitly* given a negative number, which would be ignored with the
current definition.
