ca041cd44f ethdev: change allmulticast callbacks to return status
Enabling/disabling of allmulticast mode is not always successful and
it should be taken into account to be able to handle it properly.

When correct return status is unclear from driver code, -EAGAIN is used.

9970a9ad07 ethdev: make stats and xstats reset callbacks return int
Change return value of the callbacks from void to int. Make
implementations across all drivers return negative errno
values in case of error conditions.

Both callbacks are updated together because a large number of
drivers assign the same function to both callbacks.

76f80881ef mem: add API to lock/unlock memory hotplug
Currently, the memory hotplug is locked automatically by all
memory-related _walk() functions, but sometimes locking the
memory subsystem outside of them is needed. There is no
public API to do that, so it creates a dependency on shared
memory config to be public. Fix this by introducing a new
API to lock/unlock the memory hotplug subsystem.

Create a new common file for all things mem config, and a
new API namespace rte_mcfg_*, and search-and-replace all
usages of the locks with the new API.

3f8fb60474 net/virtio: move VLAN tag insertion to Tx prepare
VLAN tag insertion should be in Tx prepare, not in Tx burst functions.
One of Tx prepare goals is to be able to do preparations in advance
(possibly on different CPU core) and then transmit it fast.
Also Tx prepare can report that a packet does not pass Tx offloads
check. E.g. has no enough headroom to insert VLAN header.

00a5ea02e1 net/virtio: add Tx preparation
Virtio requires pseudo-header checksum in TCP/UDP checksum to do
offload, but it was lost when Tx prepare is introduced. Also
rte_validate_tx_offload() should be used to validate Tx offloads.

Also it is incorrect to do virtio_tso_fix_cksum() after prepend
to mbuf without taking prepended size into account, since layer 2/3/4
lengths provide incorrect offsets after prepend.

8f37e38241 net/virtio: fix buffer leak on VLAN insert
The function rte_vlan_insert may allocate a new buffer for the
vlan header and return a different mbuf than originally passed.
In this case, the stored mbuf in txm[] array could point to wrong
buffer.

6723c0fc72 replace snprintf with strlcpy
Do a global replace of snprintf(..."%s",...) with strlcpy, adding in the
rte_string_fns.h header if needed.  The function changes in this patch were
auto-generated via command:

  spatch --sp-file devtools/cocci/strlcpy.cocci --dir . --in-place

and then the files edited using awk to add in the missing header:

  gawk -i inplace '/include <rte_/ && ! seen { \
  	print "#include <rte_string_fns.h>"; seen=1} {print}'

5c67301273 net/virtio: remove useless condition
Since previous test is for mtu < 1519 the next else if
is always true. This causes the lgtm static tool to complain.
Not a real issue, just cosmetic.

12e9e70c89 net/virtio: define avail and used flags as constants
We are consistently passing 1 as the argument in the data path,
so there is no need to define avail/used flags as function-like
macros anymore. This patch changes the avail and used flags to
constants. And a frequently used combination is also introduced.

1c8489da56 net/virtio-user: fix multi-process support
This patch fixes the multi-process support for virtio-user.
Currently virtio-user just provides some limited secondary
process supports. Only some basic operations can be done in
secondary process on virtio-user port, e.g. getting port stats.
Actions which will trigger the communication with vhost backend
can't be done in secondary process for now, as the fds are
not synced between processes. The processing of server mode
devargs is also moved into virtio_user_dev_init().
