<id>39eddb4c3970e9aadbc87b8a7cab7b4fefff077f</id>
<content type='text'>
In rare cases when an underrun occur, all macb buffers where consumed
and the netif_queue was stopped infinitely. This happens then the TGO
(transfer ongoing) bit in the TSR is set (and UND). It seems like
clening up after the underrun makes the driver and the macb hardware
end up in an inconsistent state. The result of this is that in the
following calls to macb_tx no TX buffers are released -&gt; the
netif_queue was stopped, and never woken up again.

The solution is to disable the transmitter, if TGO is set, before
clening up after the underrun, and re-enable the transmitter when the
cleaning up is done.

<title>net: Remove unused netdev arg from some NAPI interfaces.</title>

When the napi api was changed to separate its 1:1 binding to the net_device
struct, the netif_rx_[prep|schedule|complete] api failed to remove the now
vestigual net_device structure parameter.  This patch cleans up that api by
properly removing it..

The generic packet receive code takes care of setting
netdev-&gt;last_rx when necessary, for the sake of the
bonding ARP monitor.

Drivers need not do it any more.

Some cases had to be skipped over because the drivers
were making use of the -&gt;last_rx value themselves.

This converts pretty much everything to print_mac. There were
a few things that had conflicts which I have just dropped for
now, no harm done.

I've built an allyesconfig with this and looked at the files
that weren't built very carefully, but it's a huge patch.

This patch introduces mdiobus_alloc() and mdiobus_free(), and
makes all mdio bus drivers use these functions to allocate their
struct mii_bus'es dynamically.

In preparation of giving mii_bus objects a device tree presence of
their own, rename struct mii_bus's -&gt;dev argument to -&gt;parent, since
having a 'struct device *dev' that points to our parent device
conflicts with introducing a 'struct device dev' representing our own
device.

<title>netdev: bunch of drivers: avoid WARN at net/core/dev.c:1328</title>

<content type='text'>
The drivers were touching net queue before it has been started, so
without this patch, the drivers will potentially WARN at
net/core/dev.c:1328.

I don't have the hardware for the drivers below, so this patch is
untested, and thus should be carefully peer reviewed.

tc35815.c
au1000_eth.c
bfin_mac.c
macb.c
^ The four drivers are using phylib, they're calling netif_start_queue()
in open() callback. So trivially remove netif_tx_schedule_all().
Phylib will handle netif_carrier_*().

cpmac.c
fec_mpc52xx.c
fs_enet/fs_enet-main.c
sh_eth.c
^ The same as above, but these were also needlessly calling
netif_carrier_*() functions. So removed queue calls and also remove
carrier calls, since phylib will handle it. fs_enet-main.c also didn't
call netif_start_queue() at open(), this is fixed now.
