In mvneta_port_up() we enable relevant RX and TX port queues by write
queues bit map to an appropriate register.

q_map must be ZERO in the beginning of this process.

Miguel reported an skb use after free / double free in vrf_finish_output
when neigh_output returns an error. The vrf driver should return after
the call to neigh_output as it takes over the skb on error path as well.

Patch is a simplified version of Miguel's patch which was written for 4.9,
and updated to top of tree.

pull-request: bpf 2018-03-29

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix nfp to properly check max insn count while emitting
   instructions in the JIT which was wrongly comparing bytes
   against number of instructions before, from Jakub.

2) Fix for bpftool to avoid usage of hex numbers in JSON
   output since JSON doesn't accept hex numbers with 0x
   prefix, also from Jakub.

Today, driver drops received packets which are indicated as
invalid checksum by the device. Instead of dropping such packets,
pass them to the stack with CHECKSUM_NONE indication in skb.

My recent change to netvsc drive in how receive flags are handled
broke multicast.  The Hyper-v/Azure virtual interface there is not a
multicast filter list, filtering is only all or none. The driver must
enable all multicast if any multicast address is present.

Description:
Crash was reported with syzkaller pointing to lan78xx_write_reg routine.

Root-cause:
Proper cleanup of workqueues and init/setup routines was not happening
in failure conditions.

Fix:
Handled the error conditions by cleaning up the queues and init/setup
routines.

Since commit c5ad119fb6c09b0297446be05bd66602fa564758
("net: sched: pfifo_fast use skb_array") driver is exposed
to an issue where it is hitting NULL skbs while handling TX
completions. Driver uses mmiowb() to flush the writes to the
doorbell bar which is a write-combined bar, however on x86
mmiowb() does not flush the write combined buffer.

This patch fixes this problem by replacing mmiowb() with wmb()
after the write combined doorbell write so that writes are
flushed and synchronized from more than one processor.

Global pause and PFC configuration should be mutually exclusive (i.e. only
one of them at most can be set). However, once PFC was turned off,
driver automatically turned Global pause on. This is a bug.

Fix the driver behaviour to turn off PFC/Global once the user turned the
other on.

This also fixed a weird behaviour that at a current time, the profile
had both PFC and global pause configuration turned on, which is
Hardware-wise impossible and caused returning false positive indication
to query tools.

In addition, fix error code when setting global pause or PFC to change
metadata only upon successful change.

Also, removed useless debug print.
