Here's the patch. It shrinks the stack from 1152 bytes to 192 bytes (the
first version, that only did the e1000_option part, got it down to 600
bytes). About half comes from not using multiple "e1000_option"
structures, the other half comes from turning the "e1000_opt_list[]"
arrays into "static const" instead, so that gcc doesn't copy them onto the
stack.

The has Rx work check was wrong: when the FW was at the end of the page,
the driver was already at the beginning of the next page. Since the
check only validated that both driver and FW are pointing to the same
place, it concluded that there is still work to be done. This caused
some serious issues including long latency results on ping-pong test and
lockups while unloading the driver in that condition.

(Only important for USB V1 Adaptors)
If an incoming frame wasn't accepted by p54_rx function
the skb will be reused for new frames...
But, we must not forget to set the skb's data pointers into
the same state in which it was initialized by p54u_init_urbs.
Otherwise we either end up with 16 bytes less on every requeue,
or if a new frame is worthy enough to be accepted, the data is
in the wrong place (urb->transfer_buffer wasn't updated!) and mac80211
has a hard time to recognize it...

While this isn't much a problem for any PCI or ISL3887 cards/sticks,
because they don't need any extra header and therefore tx_hdr_len is

Additionally, the old logic always tx'ed cts frames (if enabled)

skb_alloc produces linear packets (using kmalloc()). That can fail,
so should we fall back to making paged skbs.
My original version of this patch always allocate paged skbs for big
packets. But that made performance drop from 8.4 seconds to 8.8
seconds on 1G lguest->Host TCP xmit. So now we only do that as a
fallback.

Add a TUNGETIFF interface so that userspace can query a
tun/tap descriptor for its name and flags.
This is needed because it is common for one app to create
a tap interface, exec another app and pass it the file
descriptor for the interface. Without TUNGETIFF the spawned
app has no way of detecting wheter the interface has e.g.
IFF_VNET_HDR set.

Now that the network stack can handle inbound packets with partial
checksums, we should no longer clobber the ip_summed field in the
loopback driver. This is because CHECKSUM_UNNECESSARY implies that
the checksum field is actually valid which is not true for loopback
packets since it's only partial (and thus complemented).
This allows packets from lo to then be SNATed to an external source
while still preserving the checksum's validity.

This patch enables TSO since the loopback device is naturally
capable of handling packets of any size. This also means that
we won't enable GSO on lo which is good until GSO is fixed to
preserve netfilter state as netfilter treats loopback packets
in a special way.

Ethtool stats are 64-bits in length. net_device_stats members are
unsigned long types. When gathering information for
a get_ethtool_stats call, the driver will call a driver-private,
inlined get_stat64() function, which returns an unsigned long value.
This call will inadvertently mask off the upper 32-bits of a stat on
32-bit machines.
This patch defines a new get_estat() inline function and modifies the
ESTAT_ADD() macro to use it.

The git commit 7c5026aa9b81dd45df8d3f4e0be73e485976a8b6 ("tg3: Add
link state reporting to UMP firmware") introduced code that waits for
previous firmware events to be serviced before attempting to submit a
new event. Unfortunately that patch contained a bug that cause the
driver to wait 2.5 seconds, rather than 2.5 milliseconds as intended.
This patch fixes that bug.
This bug revealed that not all firmware versions service driver events
though. Since we do not know which versions of the firmware do and don't
service these events, the driver needs some way to minimize the effects
of the delay. This patch solves the problem by recording a jiffies
timestamp when it submits an event to the hardware. If the jiffies
counter shows that 2.5 milliseconds have already passed, a wait is not
needed and the driver can proceed to submit a new event.

If the driver resets the chip while the APE is performing a register
access, that register access will never complete and the APE will hang
indefinitely. To prevent this race condition, the driver must acquire
an APE mutex before resetting the chip. The APE will not attempt a
register access until it acquires this lock.

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.
