In order to support a more accurate check for a PTP Rx hang where the
device can no longer timestamp received packets, we need to update, per
ring, when the last Rx timestamp was. Because of how the PTP Rx hang logic
works, the current logic is valid, but properly updating the ring variable
increases the accuracy of the check.

This patch addresses the changes needed to make LEDs work properly with

blinking for SerDes devices. Also made changes to magic number and the

When using the new bridge FDB interface to allow SR-IOV virtual function
network devices to communicate with SW bridged network devices the
physical function is placed into promiscuous mode and hardware VLAN
filtering is disabled. This defeats the ability to use VLAN tagging
to isolate user networks. When the device is in promiscuous mode and
VT mode simultaneously ensure that VLAN hardware filtering remains
enabled.

The e{uid,gid} --> {uid,gid} credentials fix conflicted with the
cleanup in net-next to now pass cred structs around.
The be2net driver had a bug fix in 'net' that overlapped with the VLAN
interface changes by Patrick McHardy in net-next.
An IGB conflict existed because in 'net' the build_skb() support was
reverted, and in 'net-next' there was a comment style fix within that
code.
Several batman-adv conflicts were resolved by making sure that all
calls to batadv_is_my_mac() are changed to have a new bat_priv first
argument.
Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO
rewrite in 'net-next', mostly overlapping changes.
Thanks to Stephen Rothwell and Antonio Quartulli for help with several
of these merge resolutions.

Add a protocol argument to the VLAN packet tagging functions. In case of HW
tagging, we need that protocol available in the ndo_start_xmit functions,
so it is stored in a new field in the skb. The new field fits into a hole

This patch actually reverts:
igb: Support using build_skb in the case that jumbo frames are disabled
The reason for reverting this patch is that it can lead to data corruption.
The following flow was pointed out by Ben Hutchings:
1. skb is forwarded to another device
2. Packet headers are modified and it's put into a queue
3. Second packet is received into the other half of this page
4. Page cannot be reused, so is DMA-unmapped
5. The DMA mapping was non-coherent, so unmap copies or invalidates
cache
The headers added in step 2 get trashed in step 5.

For 82576 MAC type, max_adj is reported as 1000000000 ppb. However, if
this value is passed to igb_ptp_adjfreq_82576, incvalue overflows out of
INCVALUE_82576_MASK, resulting in setting of zero TIMINCA.incvalue, stopping
the PHC (instead of going at twice the nominal speed).
Fix the advertised max_adj value to the largest value hardware can handle.
As there is no min_adj value available (-max_adj is used instead), this will
also prevent stopping the clock intentionally. It's probably not a big deal,
other igb MAC types don't support stopping the clock, either.

The max_vfs= option has always been self limiting to the number of VFs
supported by the device. fa44f2f1 added SR-IOV configuration via
sysfs, but in the process broke this self correction factor. The
failing path is:
igb_probe
igb_sw_init
if (max_vfs > 7) {
adapter->vfs_allocated_count = 7;
...
igb_probe_vfs
igb_enable_sriov(, max_vfs)
if (num_vfs > 7) {
err = -EPERM;
...
This leaves vfs_allocated_count = 7 and vf_data = NULL, so we bomb out
when igb_probe finally calls igb_reset. It seems like a really bad
idea, and somewhat pointless, to set vfs_allocated_count separate from
vf_data, but limiting max_vfs is enough to avoid the null pointer.

On s390 the igb driver was throwing a build error due to the fact that a frame
built using build_skb would be larger than 2K. Since this is not likely to
change at any point in the future we are better off just dropping the check
since we already had a check in igb_set_rx_buffer_len that will just disable
the usage of build_skb anyway.

After reviewing the igb and ixgbe code I realized there are a few issues in
how the code is structured. Specifically we are not checking the size of the
buffers being used in transmits and we are not using the same value to
determine when to stop or start a Tx queue. As such the code is prone to be
buggy.
This patch makes it so that we have one value DESC_NEEDED that we will use for
starting and stopping the queue. In addition we will check the size of
buffers being used when setting up a transmit so as to avoid a possible buffer
overrun if we were to receive a frame with a block of data larger than 32K in
skb->data.
