drm/i915: Remove unused file
find(1): Fix locate database updating, again. :)

This commit re-applies 83c5db2eae3d86.

I should have been more clear in its commit message that locate.updatedb
was not failing with an error if this local change wasn't kept, but that
the database was incomplete and of a much smaller size.

When testing find(1) after an upgrade, a good general rule is that
/var/db/locate.database needs to have about the same size after the
upgrade as it had before the upgrade.
nrelease: Fix two pkgsrc references which i had forgotten in c36c5990ecc.
mxge: Implement multiple TX queue support

To enable multiple multiple TX queues, you will need to set tunable
hw.mxge.num_slices or hw.mxgeX.num_slices to 0 or any value >1.

If you want only enable multiple RX queues bu only one TX queue,
in addition to the above tunables tunable hw.mxge.multi_tx should
be set to 0.
mxge: Use chip private input hash instead of standard RSS input hash

This restores RX performance when multiple RX queues are enable.

If the stardard RSS input hash is used, the chip's firmware will compute
the RSS hash (*); this kinda explains why using standard RSS input hash
hurts RX performance greatly.

Sysctl hw.mxgeX.use_rss is added to turn on standard RSS input hash.
It is disabled by default.  It is also controlled globally by tunable
hw.mxge.use_rss.
