e1000e: If ASPM L0s needs to be disabled, do it prior to enabling device
Based on a patch from Naga Chumbalkar <nagananda.chumbalkar@hp.com>:
If ASPM L0s needs to be disabled due to HW errata, do it prior to
"enabling" the device. This way if the kernel ever defaults its
aspm_policy to POLICY_POWERSAVE, then the e1000e driver will get a
chance to disable ASPM on the misbehaving device *prior* to calling
pci_enable_device_mem(). This will be useful in situations
where the BIOS indicates ASPM support on the server by clearing the
ACPI FADT "ASPM Controls" bit.
Note:
The kernel (2.6.38) currently uses the BIOS "default" as its aspm_policy.
However, Linux distros can diverge from that and set the default to
"powersave".
v2: o cleanup namespace pollution of e1000e_disable_aspm(),
o fix type and initialization of the new aspm_disable_flag in a few
functions, and
o redefine FLAG2_DISABLE_ASPM_L0S to the first unused bit in
adapter->flags2.

net: ksz884x: convert to hw_features
This also fixes possible race when changing receive checksum state
and removes IPV6_CSUM_GEN_HACK as it's always set.
BTW, The claim about fake IPV6 checksum looks dubious. If that were true,
then there's a problem in networking core and should be fixed there and not
in random drivers.
BTW#2, there's no MAINTAINERS entry for this driver. I assume this driver
is supported by Micrel?

net: stmmac: convert to hw_features
This also removes TSO as it's made fully in software --- better to leave this
to networking core.
If the MAC features can be detected at probe time and not at open, then
stmmac_fix_features could be simplified by limiting hw_features. That's
also better for users as they don't see offloads being togglable but
never turned on.
Redundant fallbacks for TX csum are removed as it's already handled
by network core.

Disable rp_filter for IPsec packets
The reverse path filter interferes with IPsec subnet-to-subnet tunnels,
especially when the link to the IPsec peer is on an interface other than
the one hosting the default route.
With dynamic routing, where the peer might be reachable through eth0
today and eth1 tomorrow, it's difficult to keep rp_filter enabled unless
fake routes to the remote subnets are configured on the interface
currently used to reach the peer.
IPsec provides a much stronger anti-spoofing policy than rp_filter, so
this patch disables the rp_filter for packets with a security path.

cnic: Fix rtnl deadlock
When cnic_stop_hw() -> cnic_cm_stop_bnx2x_hw() is called under rtnl_lock()
from NETDEV_DOWN event, it waits for cnic_delete_task() to complete.
It will deadlock when cnic_delete_task() takes rtnl_lock() before
calling cnic_ulp_stop_one().
We fix it by removing the rtnl_lock() in cnic_delete_task().
cnic_ulp_stop_one() has mutex and atomic bit ops to prevent important
operations from being done more than once, so it is not necessary to take
rtnl_lock().

p54: Initialize extra_len in p54_tx_80211
This patch fixes a very serious off-by-one bug in
the driver, which could leave the device in an
unresponsive state.
The problem was that the extra_len variable [used to
reserve extra scratch buffer space for the firmware]
was left uninitialized. Because p54_assign_address
later needs the value to reserve additional space,
the resulting frame could be to big for the small
device's memory window and everything would
immediately come to a grinding halt.
