When there is heavy traffic and the cable is pulled, the driver must reset
the adapter to flush the Tx queue in hardware. This causes the reset path
to be scheduled and logs the message "Reset adapter" which could be mis-
interpreted as an error by the user. Change how the reset path is invoked
for this scenario by using the same method done in an existing work-around
for 80003es2lan (i.e. set a flag and if the flag is set in the reset code
do not log the "Reset adapter" message since the reset is expected).
Re-name the FLAG_RX_RESTART_NOW to FLAG_RESTART_NOW since it is used for
resets in both the Rx and Tx specific code.

When data blocks are written to the EEPROM, the HW/SW/FW semaphore must be
held for the duration. With large data blocks on 80003es2lan, 82571 and

the semaphore and consequently ownership of writes to the EEPROM.
Instead, acquire and release the semaphore for each page of the block

Since submit 621b4d6 the bnx2x driver support FW GRO.
However, when using the device with GRO enabled in bridging
scenarios throughput is very low, as the bridge expects all
incoming packets to be passed with CHECKSUM_PARTIAL -
a demand which is satisfied by the SW GRO implementation,
but was missed in the bnx2x driver implementation (which returned
CHECKSUM_UNNECESSARY).
Now, given that the traffic is supported by FW GRO (TCP/IP),
the bnx2x driver calculates the pseudo checksum by itself,
passing skbs with CHECKSUM_PARTIAL and giving a much better
throughput when receiving GRO traffic.

This patch corrects some problems with LSM/SELinux that were introduced
with the multiqueue patchset. The problem stems from the fact that the
multiqueue work changed the relationship between the tun device and its
associated socket; before the socket persisted for the life of the
device, however after the multiqueue changes the socket only persisted
for the life of the userspace connection (fd open). For non-persistent
devices this is not an issue, but for persistent devices this can cause
the tun device to lose its SELinux label.
We correct this problem by adding an opaque LSM security blob to the
tun device struct which allows us to have the LSM security state, e.g.
SELinux labeling information, persist for the lifetime of the tun
device. In the process we tweak the LSM hooks to work with this new
approach to TUN device/socket labeling and introduce a new LSM hook,
security_tun_dev_attach_queue(), to approve requests to attach to a
TUN queue via TUNSETQUEUE.
The SELinux code has been adjusted to match the new LSM hooks, the
other LSMs do not make use of the LSM TUN controls. This patch makes
use of the recently added "tun_socket:attach_queue" permission to
restrict access to the TUNSETQUEUE operation. On older SELinux
policies which do not define the "tun_socket:attach_queue" permission
the access control decision for TUNSETQUEUE will be handled according
to the SELinux policy's unknown permission setting.

The flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.
