This patch allows the rndis_wlan driver to connect to TKIP PSK

the IEs and sends them back to userspace using wireless events. Tested
on a few wireless networks I have access to. Based on the similar

rt2x00lib_beacondone() is called from interrupt context,
this means we cannot use the mac80211 interface iterator
that uses the rtnl lock (since that uses a mutex which can sleep).
Instead we should use the atomic mac80211 interface iterator.

Link quality estimation became quite low for all rt2x00 drivers
because the number of retries it took to send the frame were
counted as failure.
This does not correspond to the legacy driver link quality calculation,
by not counting it we will send somewhat more optimistic values to
mac80211.

The static function max2820_rf_set_channel is called with conf == NULL
within its compilation unit. Originally this defaulted to b/g channel
1, but "cfg80211 API for channels/bitrates, mac80211 and driver

dropped this check. This patch minimally restores the expected

if (fep->ops == NULL) {
printk(KERN_ERR DRV_MODULE_NAME
": %s No matching ops found (%d).\n",
ndev->name, fpi->fs_no);
err = -EINVAL;
goto err;
}
This code implies that at the point of err, fep->ops can be NULL, so an
extra test is needed before dereferencing this value.

This patch adds netpoll support for the uli526x ethernet driver --
simply call the interrupt handler for polling.
To do this without disable_irq()/enable_irq() pair we should fully
protect the handler. Luckily, it's already using irqsave spinlock,
the only unprotected place is interrupts re-enabling write. It was
safe to re-enable interrupts without holding the spinlock, but with
netpoll possibility now it doesn't seem so.
Patch was tested using netconsole and KGDBoE.

IPv4 would work with this driver only with static arp table entries,
the patch reverts a padto introduced in
commit 26a17b7bbb
sc92031: start transmit return value bugfix
The padto does not work because the driver code evaluates `len' later on and
there are cases where skb->len is not updated accordingly.
This was observed with ARP frames (skb->len = 42 bytes, !skb_cloned(),
skb_tailroom = 84 bytes). Then in skb_pad(), the first condition is true, where
skb->len is not updated. As a consequence, the driver uses 42 bytes instead of
the 60 bytes, and the ARP frame never makes it onto the wire.
