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.

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

Packets can be left in the RX ring if the NAPI budget is reached.
This is caused by storing the latest rx index at the beginning of

if the budget is reached and so some packets in the RX ring may rot
when we later check for more work using this stored rx index.
The fix is to not store this latest hw index and only store the

The bug is in the code in bnx2_set_power_state() that assumes copper
devices when setting up WoL. This is no longer true after adding WoL
support for Serdes devices.

Need to read and store sblk->status_idx before checking for more work.
The status idx is later written back to the hardware when enabling
interrupts to acknowledge how much work has been processed. If the
order is reversed, we can end up acknowledging work we haven't
processed.
When completing bnx2_poll(), we should always break out of the while
loop and return work_done instead of returning 0.

In order for the list handling in net_rx_action() to be
correct, drivers must follow certain rules as stated by
this comment in net_rx_action():
/* Drivers must not modify the NAPI state if they
* consume the entire weight. In such cases this code
* still "owns" the NAPI instance and therefore can
* move the instance around on the list at-will.
*/
A few drivers do not do this because they mix the budget checks
with reading hardware state, resulting in crashes like the one
reported by takano@axe-inc.co.jp.
BNX2 and TG3 are taken care of here, SKY2 fix is from Stephen
Hemminger.
