Benjamin Li ac392abce9 bnx2: Remove timer_interval field from the bnx2 structure
The timer_interval field is only assigned once, and never reassigned.
We can safely replace all instances of the timer_interval with a
constant value.

Michael Chan f22828e89f bnx2: Reinsert VLAN tag when necessary.
In certain cases when ASF or other management firmware is running, the
chip may be configured to always strip out the VLAN tag even when
VLAN acceleration is not enabled.  This causes some VLAN tagged
packets to be received by the host stack without any knowledge that
the original packet was VLAN tagged.

We fix this by re-inserting the VLAN tag into the packet when necessary.

David S. Miller 4bb073c0e3 net: Eliminate flush_scheduled_work() calls while RTNL is held.
If the RTNL is held when we invoke flush_scheduled_work() we could
deadlock.  One such case is linkwatch, it is a work struct which tries
to grab the RTNL semaphore.

The most common case are net driver ->stop() methods.  The
simplest conversion is to instead use cancel_{delayed_}work_sync()
explicitly on the various work struct the driver uses.

This is an OK transformation because these work structs are doing
things like resetting the chip, restarting link negotiation, and so
forth.  And if we're bringing down the device, we're about to turn the
chip off and reset it anways.  So if we cancel a pending work event,
that's fine here.

Some drivers were working around this deadlock by using a msleep()
polling loop of some sort, and those cases are converted to instead
use cancel_{delayed_}work_sync() as well.

Michael Chan 9a120bc570 bnx2: Allow phy reset to be skipped during chip reset.
Andy Gospodarek <andy@greyhouse.net> found that netconsole would
panic when resetting bnx2 devices.

>From Andy:
"The issue is the bnx2_set_link in bnx2_init_nic will print a link-status
message before we are fully initialized and ready to start polling.
Polling is currently disabled in this state, but since the
__LINK_STATE_RX_SCHED is overloaded to not only try and disable polling
but also to make the system aware there is something waiting to be
polled, we really have to fix this in drivers.

The problematic call is the one to netif_rx_complete as it tries to
remove an entry from the poll_list when there isn't one."

While this netconsole problem should be fixed separately, we really
should not reset the PHY when changing ring sizes, MTU, or other
similar settings.  The PHY reset causes several seconds of unnecessary
link disruptions.
