This reverts commit 0a4e9ce17ba77847e5a9f87eed3c0ba46e3f82eb.
The code was developed and tested on an MSC313E SoC, which seems to be
half-way between the AT91RM9200 and the AT91SAM9260 in that it supports
both the 2-descriptors mode and a Tx ring.
It turns out that after the code was merged I could notice that the
controller would sometimes lock up, and only when dealing with sustained
bidirectional transfers, in which case it would report a Tx overrun
condition right after having reported being ready, and will stop sending
even after the status is cleared (a down/up cycle fixes it though).
After adding lots of traces I couldn't spot a sequence pattern allowing
to predict that this situation would happen. The chip comes with no
documentation and other bits are often reported with no conclusive
pattern either.
It is possible that my change is wrong just like it is possible that
the controller on the chip is bogus or at least unpredictable based on
existing docs from other chips. I do not have an RM9200 at hand to test
at the moment and a few tests run on a more recent 9G20 indicate that
this code path cannot be used there to test the code on a 3rd platform.
Since the MSC313E works fine in the single-descriptor mode, and that
people using the old RM9200 very likely favor stability over performance,
better revert this patch until we can test it on the original platform
this part of the driver was written for. Note that the reverted patch
was actually tested on MSC313E.

Packets sent by rmnet to the real device have variable MAP header
lengths based on the data format configured. This patch adds checks
to ensure that the real device MTU is sufficient to transmit the MAP
packet comprising of the MAP header and the IP packet. This check
is enforced when rmnet devices are created and updated and during
MTU updates of both the rmnet and real device.
Additionally, rmnet devices now have a default MTU configured which
accounts for the real device MTU and the headroom based on the data
format.

Currently, the driver gets the max rss size from configuration
file when initialization. Both the PF and VF share the same
max rss size, and no more than 128.
For DEVICE_VERSION_V3, the max rss size for PF can be up to
512, so there is a new field in configuration file to store it,
the old filed is used for VF.
To be compatible with boards using old configure file, the PF
will use the old filed if the one is zero.

The page recycle code, incorrectly, relied on that a page fragment
could not be freed inside xdp_do_redirect(). This assumption leads to
that page fragments that are used by the stack/XDP redirect can be
reused and overwritten.
To avoid this, store the page count prior invoking xdp_do_redirect().
Longer explanation:
Intel NICs have a recycle mechanism. The main idea is that a page is
split into two parts. One part is owned by the driver, one part might
be owned by someone else, such as the stack.
t0: Page is allocated, and put on the Rx ring
+---------------
used by NIC ->| upper buffer
(rx_buffer) +---------------
| lower buffer
+---------------
page count == USHRT_MAX
rx_buffer->pagecnt_bias == USHRT_MAX
t1: Buffer is received, and passed to the stack (e.g.)
+---------------
| upper buff (skb)
+---------------
used by NIC ->| lower buffer
(rx_buffer) +---------------
page count == USHRT_MAX
rx_buffer->pagecnt_bias == USHRT_MAX - 1
t2: Buffer is received, and redirected
+---------------
| upper buff (skb)
+---------------
used by NIC ->| lower buffer
(rx_buffer) +---------------
Now, prior calling xdp_do_redirect():
page count == USHRT_MAX
rx_buffer->pagecnt_bias == USHRT_MAX - 2
This means that buffer *cannot* be flipped/reused, because the skb is
still using it.
The problem arises when xdp_do_redirect() actually frees the
segment. Then we get:
page count == USHRT_MAX - 1
rx_buffer->pagecnt_bias == USHRT_MAX - 2
From a recycle perspective, the buffer can be flipped and reused,
which means that the skb data area is passed to the Rx HW ring!
To work around this, the page count is stored prior calling
xdp_do_redirect().
Note that this is not optimal, since the NIC could actually reuse the
"lower buffer" again. However, then we need to track whether
XDP_REDIRECT consumed the buffer or not.

Since we share the transmit queue with the network stack,
it is possible that we run into a transmit queue timeout.
This will reset the queue.
This happens under high load when XDP is using the
transmit queue pretty much exclusively.
netdev_start_xmit() sets the trans_start variable of the
transmit queue to jiffies which is later utilized by dev_watchdog(),
so to avoid timeout, let stack know that XDP xmit happened by
bumping the trans_start within XDP Tx routines to jiffies.
