e1000e: drop stats lock

2008-10-03T01:28:12+00:00

the stats lock is left over from e1000, e1000e no longer
has the adjust tbi stats function that required the addition
of the stats lock to begin with.

adding a mutex to acquire_swflag helped catch this one too.

e1000e: remove phy read from inside spinlock

2008-10-03T01:28:12+00:00

thanks to tglx, we're finding some interesting reentrancy issues.
this patch removes the phy read from inside a spinlock, paving
the way for removing the spinlock completely.  The phy read was
only feeding a statistic that wasn't used.

e1000e: do not ever sleep in interrupt context

2008-10-03T01:28:12+00:00

e1000e was apparently calling two functions that attempted to reserve
the SWFLAG bit for exclusive (to hardware and firmware) access to
the PHY and NVM (aka eeprom).  These accesses could possibly call
msleep to wait for the resource which is not allowed from interrupt
context.

e1000e: write protect ICHx NVM to prevent malicious write/erase

2008-10-02T00:31:25+00:00

Set the hardware to ignore all write/erase cycles to the GbE region in
the ICHx NVM.  This feature can be disabled by the WriteProtectNVM module
parameter (enabled by default) only after a hardware reset, but
the machine must be power cycled before trying to enable writes.

e1000e: test for unusable MSI support

2008-08-14T08:42:29+00:00

Some systems do not like 82571/2 use of 16-bit MSI messages and some
other systems claim to support MSI, but neither really works.  Setup a
test MSI handler to detect whether or not MSI is working properly, and
if not, fallback to legacy INTx interrupts.

e1000e: increase minimum frame size allowed

2008-08-14T08:40:20+00:00

Setting an MTU value below 68 was disabling the network connection and
would not reconnect until the driver was reloaded.  Prevent changing the
MTU to anything below 68.

e1000e: Use skb_copy_to_linear_data_offset introduced in 2.6.22

2008-08-14T08:40:10+00:00

The e1000e driver was based on a version of e1000 prior to acme's
introduction of skb_copy_to_linear_data_offset, and was submitted
after acme went through and coverted all the drivers to use it.

e1000e: remove inapplicable test for ioport

2008-08-07T05:54:55+00:00

There are currently no devices supported by the e1000e driver which need
ioport resources, remove the test for it and all unnecessary code
associated with it (struct e1000_adapter elements, local variables, etc.)
