e1000e: use BIT() macro for bit defines

2016-05-13T22:15:36+00:00

This prevents signed bitshift issues when the shift would overwrite the
signed bit, and prevents making this mistake in the future when copying
and modifying code.

Use GENMASK or the unsigned postfix for cases which aren't suitable for
BIT() macro.

e1000e: Failure to write SHRA turns on PROMISC mode

2014-05-27T06:53:11+00:00

Previously, the check to turn on promiscuous mode only took into account
the total number of SHared Receive Address (SHRA) registers and if the
request was for a register within that range.  It is possible that the
Management Engine might have locked a number of SHRA and not allowed a
new address to be written to the requested register.

Add a function to determine the number of unlocked SHRA registers.  Then
determine if the number of registers available is sufficient for our needs,
if not then return -ENOMEM so that UNICAST PROMISC mode is activated.

Since the method by which ME claims SHRA registers is non-deterministic,
also add a return value to the function attempting to write an address
to a SHRA, and return a -E1000_ERR_CONFIG if the write fails.  The error
will be passed up the function chain and allow the driver to also set
UNICAST PROMISC when this happens.

e1000e: fix LED blink logic for designs with LEDs driven by cathode

2013-03-28T06:32:06+00:00

When the LEDs are driven by cathode, the bit logic is reversed.  Use the
LED Invert bit to invert the logic.  Cleanup use of a magic number and
change the for loop increment to reduce the number of shifts.

e1000e: cleanup USLEEP_RANGE checkpatch checks

2013-03-08T09:28:59+00:00

Resolve strict checkpatch USLEEP_RANGE checks by converting delays and
sleeps as described in ./Documentation/timers/timers-howto.txt.  Three
other violations of the text have also been fixed.

CHECK:USLEEP_RANGE: usleep_range is preferred over udelay; see

e1000e: use generic IEEE MII definitions

2013-02-01T06:34:59+00:00

For standard IEEE MII-compatible transceivers, the kernel has generic
register and bit definitions.  Use those instead of redundant local
defines.

Do not replace references of MII_CR_SPEED_10 with BMCR_SPEED10 (0x0000)
when it is not necessary (i.e. when it is bitwise OR'ed with another
value).

Some whitespace issues in the surrounding context of the above changes are
also cleaned up.
