If RX lockup workaround is enabled, fxp(4) will periodically reset
the controller to workaround silicon bug of i82557. Each reset will
re-establish link which in turn triggers MII status change
callback. The callback will try to reconfigure controller if the
controller is not i82557 to enable flow-control. This caused
endless link UP/DOWN when the workaround was enabled on non-i82557
controller.
To fix the issue, apply RX lockup workaround only for i82557.
Previously it blindly checked undocumented EEPROM location such
that it sometimes enabled the workaround for other controllers. At
this time, only i82557 is known to have the silicon bug.
This fixes a regression introduced in r215906 which enabled flow
control support for all controllers except i82557.

Merge revision 211236 form current:
Allow interrupt driven config hooks to be registered from config hook callbacks.
Interrupt driven configuration hooks serve two purposes: they are a
mechanism for registering for a callback that is invoked once interrupt
services are available, and they hold off root device selection so long
as any configuration hooks are still active. Before this change, it was
not possible to safely register additional hooks from the context of a
configuration hook callback. The need for this feature arises when
interrupts are required to discover new devices (e.g. access to the XenStore
to find para-virtualized devices) which in turn also require the ability
to hold off root device selection until some lengthy, interrupt driven,
configuration task has completed (e.g. Xen front/back device driver
negotiation).
More specifically, the mutex protecting the list of active configuration
hooks is never held during a callback, and static information is used
to ensure proper ordering and only a single callback to each hook even
when faced with registration or removal of a hook during an active run.
