Rather than using the Receive All Frames (RAF) bit to enable promiscuous
mode, use the Promiscuous (PR) bit. This lowers overhead at runtime as
we let the hardware process the packets that should actually be checked.

IP checksum is based on 16-bit one's complement algorithm, so to deduce a
value from checksum is equal to add its complement.
Unfortunately, the Blackfin on-chip MAC checksum logic only works when the
IP packet has a header length of 20 bytes. This is true for most IPv4
packets, but not for IPv6 packets or IPv4 packets which use header options.
So only use the hardware checksum when appropriate.

The skb buffer isn't actually used until we finish transferring and pass
it up to higher layers, so only invalidate the range once before we start
receiving actual data. This also avoids the problem with data invalidating
on Blackfin systems -- there is no invalidate-only, just invalidate+flush.
So when running in writeback mode, there is the small (but not uncommon)
possibility of the flush overwriting valid DMA-ed data from the cache.

Using this driver can cause unaligned accesses in the IP layer
This has been fixed by aligning the skb data correctly using the

Some RNDIS devices don't respond on the control channel until polled
on the status channel. In particular, this was reported to be the
case for the 2Wire HomePortal 1000SW.
This is roughly based on a patch by John Carr <john.carr@unrouted.co.uk>
which is reported to be needed for use with some Windows Mobile devices
and which is currently applied by Mandriva.

Allocating memory can fail, and since we have the memory we need
in sky2_resume when sky2_suspend is called, just stop the hardware
without freeing the memory it's using.
This avoids the possibility of failing because we can't allocate
memory in sky2_resume(), and allows sharing code with sky2_restart().

we stop the queue and NAPI is disabled.

would fire a WARN_ON when adding the 15th. The WARN_ON in this

This patch removes from drivers/net/ all the unnecessary
return; statements that precede the last closing brace of
void functions.
It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.
It also does not remove null void functions with return.
Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

i) Fixes a bug where e1000_sw_lcd_config_ich8lan() was calling
e1000_lan_init_done_ich8lan() to poll the STATUS.LAN_INIT_DONE bit to
make sure the MAC had completed the PHY configuration. However,
e1000_lan_init_done_ich8lan() had already been called in one of the two
places where PHY reset occurs for ICHx/PCHx parts, which caused the second
call to busy-wait for 150 msec because the LAN_INIT_DONE bit had already
been checked and cleared.
ii) Cleanup the two separate PHY reset code paths, i.e. the full-chip reset
in e1000_reset_hw_ich8lan() and the PHY-only reset in
e1000_phy_hw_reset_ich8lan(). There was duplicate code in both paths to be
performed post-reset that are now combined into one new function -
e1000_post_phy_reset_ich8lan(). This cleanup also included moving the
clearing of the PHY Reset Asserted bit in the STATUS register (now done for
all ICH/PCH parts) and the check for the indication from h/w that basic
configuration has completed back to where it previously was in
e1000_get_cfg_done_ich8lan().
iii) Corrected a few comments

The mac->arc_subsystem was being incorrectly used to flag whether or not
manageability was enabled when it should only be used to state whether the
ARC (Host interface) subsystem is available on a particular MAC _and_ only
valid when any manageability is enabled. The ARC subsystem is currently
only available on 80003es2lan and 82573 parts supported by the driver.
A new flag, has_fwsm, is introduced to be used when checking if
manageability is enabled but only on parts that acutally have an FWSM
register. While the above parts have an FWSM register, there are other
parts that have FWSM but do not have support for the ARC subsystem,
namely 82571/2 and ICHx/PCH.
And then there are parts that have manageability, but do not have either
FWSM register or support for the ARC subsystem - these are 82574 and 82583.
For 80003es2lan, 82571/2/3 and ICH/PCH parts, this patch makes no
functional changes, it only corrects the usage of the manageability flags.
For 82574 and 82583, it fixes the incorrect accesses of the non-existent
FWSM register and ARC subsystem as well as corrects the check for
management pass-through.
