WakeOnLan was broken in this driver because gp->asleep_wol is a 1-bit
bitfield and it was being assigned WAKE_MAGIC, which is (1 << 5).
gp->asleep_wol remains 0 and the machine never wakes up. Fixed by casting
gp->wake_on_lan to bool. Tested on an iBook G4.

tcp_adv_win_scale default value is 2, meaning we expect a good citizen
skb to have skb->len / skb->truesize ratio of 75% (3/4)
In 2.6 kernels we (mis)accounted for typical MSS=1460 frame :
1536 + 64 + 256 = 1856 'estimated truesize', and 1856 * 3/4 = 1392.
So these skbs were considered as not bloated.
With recent truesize fixes, a typical MSS=1460 frame truesize is now the
more precise :
2048 + 256 = 2304. But 2304 * 3/4 = 1728.
So these skb are not good citizen anymore, because 1460 < 1728
(GRO can escape this problem because it build skbs with a too low
truesize.)
This also means tcp advertises a too optimistic window for a given
allocated rcvspace : When receiving frames, sk_rmem_alloc can hit
sk_rcvbuf limit and we call tcp_prune_queue()/tcp_collapse() too often,
especially when application is slow to drain its receive queue or in
case of losses (netperf is fast, scp is slow). This is a major latency
source.
We should adjust the len/truesize ratio to 50% instead of 75%
This patch :
1) changes tcp_adv_win_scale default to 1 instead of 2
2) increase tcp_rmem[2] limit from 4MB to 6MB to take into account
better truesize tracking and to allow autotuning tcp receive window to
reach same value than before. Note that same amount of kernel memory is
consumed compared to 2.6 kernels.

I just noticed after some recent updates, that the init path for the drop
monitor protocol has a minor error. drop monitor maintains a per cpu structure,
that gets initalized from a single cpu. Normally this is fine, as the protocol
isn't in use yet, but I recently made a change that causes a failed skb
allocation to reschedule itself . Given the current code, the implication is
that this workqueue reschedule will take place on the wrong cpu. If drop
monitor is used early during the boot process, its possible that two cpus will
access a single per-cpu structure in parallel, possibly leading to data
corruption.
This patch fixes the situation, by storing the cpu number that a given instance
of this per-cpu data should be accessed from. In the case of a need for a
reschedule, the cpu stored in the struct is assigned the rescheule, rather than
the currently executing cpu
Tested successfully by myself.

Bug: The VLAN bit of the MAC RX Status Word is unreliable in several older
supported chips. Sometimes the VLAN bit is not set for valid VLAN packets
and also sometimes the VLAN bit is set for non-VLAN packets that came after
a VLAN packet. This results in a receive length error when VLAN hardware
tagging is enabled.
Fix: Variation on original fix proposed by Mirko.
The VLAN information is decoded in the status loop, and can be
applied to the received SKB there. This eliminates the need for the
separate tag field in the interface data structure. The tag has to
be copied and cleared if packet is copied. This version checked out
with vlan and normal traffic.
Note: vlan_tx_tag_present should be renamed vlan_tag_present, but that
is outside scope of this.

The driver calls cxgb_vlan_mode() from init_one(). This calls into
synchronize_rx(), which locks all the q locks, but the q locks are not
initialized until cxgb_up() -> setup_sge_qsets(). So move the call to
cxgb_vlan_mode() into cxgb_up(), after the call to setup_sge_qsets().
We also move the body of these functions up higher to avoid having to
a forward declaration.
This was found because of the lockdep warning:

With the support to bounce buffer added, the skb is coming as nonlinear in the
case of non-DDPed data frames for FCoE, which is mostly ok as the FCoE stack
would take care of that. However, for target mode, we have to set the FC CRC
and FC EOF field to allow the protocol stack to not drop the frame for the last
data frame of that sequence. So fix this by linearizing the skb first before
doing skb_put().

It stems from holding a spinlock (trace_state_lock) while attempting to register
or unregister tracepoint hooks, making in_atomic() true in this context, leading
to the warning when the tracepoint calls might_sleep() while its taking a mutex.
Since we only use the trace_state_lock to prevent trace protocol state races, as
well as hardware stat list updates on an rcu write side, we can just convert the
spinlock to a mutex to avoid this problem.

The dl2k driver's rio_ioctl call has a few issues:
- No permissions checking
- Implements SIOCGMIIREG and SIOCGMIIREG using the SIOCDEVPRIVATE numbers
- Has a few ioctls that may have been used for debugging at one point
but have no place in the kernel proper.
This patch removes all but the MII ioctls, renumbers them to use the
standard ones, and adds the proper permission check for SIOCSMIIREG.
We can also get rid of the dl2k-specific struct mii_data in favor of
the generic struct mii_ioctl_data.
Since we have the phyid on hand, we can add the SIOCGMIIPHY ioctl too.
Most of the MII code for the driver could probably be converted to use
the generic MII library but I don't have a device to test the results.
