mac80211: in IBSS use the Auth frame to trigger STA reinsertion

In case of a node re-joining the cell the sta_info structure belonging to it is
first destroyed and then reinserted. In this way its internal state is reset.

The joining operation is recognised thank the Auth frame being received.

This operation is helpful in case of a node being rebooted that is joining the
ad-hoc cell again, before its purge timeout on other nodes expires.

tg3: Fix single-vector MSI-X code

Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
enabled.  However, kdump only enables one CPU in the new environment,
thus causing tg3 to abort MSI-X setup.  When the driver attempts to
enable INTA or MSI interrupt modes on a kdump kernel, interrupt
delivery fails.

This patch attempts to workaround the problem by forcing the driver
to enable a single MSI-X interrupt.  In such a configuration, the
device's multivector interrupt mode must be disabled.
