643fba7707 net/vmxnet3: add v4 boot and guest UDP RSS config
This patch introduces:
- VMxnet3 v4 negotiation and,
- entirely guest-driven UDP RSS support.

VMxnet3 v3 already has UDP RSS support, however it
depends on hypervisor provisioning on the VM through
ESX specific flags, which are not transparent or known
to the guest later on.

Vmxnet3 v4 introduces a new API transaction which allows
configuring RSS entirely from the guest. This API must be
invoked after device shared mem region is initialized.

IPv4 ESP RSS (SPI based) is also available, but currently
there are no ESP RSS definitions on rte_eth layer to
handle that.

d6db681bf9 drivers/net: fix several Tx prepare functions
Since below commit, several tx_prep functions are broken, they fail to
pass supported Tx offload features check:
PKT_TX_IPVx must be set when any PKT_TX_L4 checksum is requested,
but these values are not present in the mask of supported Tx offloads
of several drivers that advertise PKT_TX_L4_MASK.
So any packet sent to those drivers with a L4 checksum request and
one of PKT_TX_IPVx bit set is rejected by the tx prepare function.

15febafdd4 drivers/net: set close behaviour flag at probing
The ethdev flag RTE_ETH_DEV_CLOSE_REMOVE is set for drivers
having migrated to the new behaviour of rte_eth_dev_close().

As any other flag, it can be useful to know about its value
as soon as the port is probed.
Unfortunately, it was set inside the close operation,
just before being erased by memset() in rte_eth_dev_release_port().
The flag assignment is moved to the probing stage, so it can
be checked by the application in order to anticipate the behaviour.

6c99085d97 net/vmxnet3: fix hot-unplug
The vmxnet3 driver can't call back into dev_close(), and possibly
dev_stop(), in dev_uninit().  When dev_uninit() is called, anything
that those routines would want to clean up has already been released.
Further, for complete cleanup, it is necessary to release any of the
queue resources during dev_close().
This allows a vmxnet3 device to be hot-unplugged without leaking
queues.
Also set RTE_ETH_DEV_CLOSE_REMOVE on close so that the port resources
can be deallocated.
Return EBUSY if remove is called before stop.

5e046832f1 ethdev: rename memzones allocated for DMA
The helper rte_eth_dma_zone_reserve() is called by PMDs
when probing a new port.
It creates a new memzone with an unique name.
The name of this memzone was using the name of the driver
doing the probe.

In order to avoid assigning the driver before the end of the probing,
the driver name is removed from these memzone names.
The ethdev name (data->name) is not used because it may be too long
and may be not set at this stage of probing.

30f77abecd net/vmxnet3: support stats reset
'stats_reset()' callback was missing because the device backend doesn't
support it.

This commit adds a workaround to this and implements the callback by
taking a snapshot of the stats (SNAPSHOT) each time 'stats_reset()'
is called.  When getting stats with 'stats_get()', hw stats which
always increase reduce SNAPSHOT stats.
That's how we get the "real" stats since the last 'stats_reset()'.

323e7b667f ethdev: make default behavior CRC strip on Rx
Removed DEV_RX_OFFLOAD_CRC_STRIP offload flag.
Without any specific Rx offload flag, default behavior by PMDs is to
strip CRC.

PMDs that support keeping CRC should advertise DEV_RX_OFFLOAD_KEEP_CRC
Rx offload capability.

Applications that require keeping CRC should check PMD capability first
and if it is supported can enable this feature by setting
DEV_RX_OFFLOAD_KEEP_CRC in Rx offload flag in rte_eth_dev_configure()

ab3ce1e0c1 ethdev: remove old offload API
In DPDK 17.11, the ethdev offloads API has changed:
	commit cba7f53b71 ("ethdev: introduce Tx queue offloads API")
	commit ce17eddefc ("ethdev: introduce Rx queue offloads API")
The new API is documented in the programmer's guide:
	http://doc.dpdk.org/guides/prog_guide/poll_mode_drv.html#hardware-offload

For reminder, the main concepts in the new API were:
	- All offloads are disabled by default
	- Distinction between per port and per queue offloads.

The transition bits are now removed:
	- Translation of the old API in ethdev
	- rte_eth_conf.rxmode.ignore_offload_bitfield
	- ETH_TXQ_FLAGS_IGNORE

The old API bits are now removed:
	- Rx per-port rte_eth_conf.rxmode.[bit-fields]
	- Tx per-queue rte_eth_txconf.txq_flags
	- ETH_TXQ_FLAGS_NO*

70815c9eca ethdev: add new offload flag to keep CRC
DEV_RX_OFFLOAD_KEEP_CRC offload flag is added. PMDs that support
keeping CRC should advertise this offload capability.

DEV_RX_OFFLOAD_CRC_STRIP flag will remain one more release
default behavior in PMDs are to keep the CRC until this flag removed

Until DEV_RX_OFFLOAD_CRC_STRIP flag is removed:
- Setting both KEEP_CRC & CRC_STRIP is INVALID
- Setting only CRC_STRIP PMD should strip the CRC
- Setting only KEEP_CRC PMD should keep the CRC
- Not setting both PMD should keep the CRC

A helper function rte_eth_dev_is_keep_crc() has been added to be able to
change the no flag behavior with minimal changes in PMDs.

The PMDs that doesn't report the DEV_RX_OFFLOAD_KEEP_CRC offload can
remove rte_eth_dev_is_keep_crc() checks next release, related code
commented to help the maintenance task.

And DEV_RX_OFFLOAD_CRC_STRIP has been added to virtual drivers since
they don't use CRC at all, when an application requires this offload
virtual PMDs should not return error.

a4996bd89c ethdev: new Rx/Tx offloads API
This patch check if a input requested offloading is valid or not.
Any reuqested offloading must be supported in the device capabilities.
Any offloading is disabled by default if it is not set in the parameter
dev_conf->[rt]xmode.offloads to rte_eth_dev_configure() and
[rt]x_conf->offloads to rte_eth_[rt]x_queue_setup().
If any offloading is enabled in rte_eth_dev_configure() by application,
it is enabled on all queues no matter whether it is per-queue or
per-port type and no matter whether it is set or cleared in
[rt]x_conf->offloads to rte_eth_[rt]x_queue_setup().
If a per-queue offloading hasn't be enabled in rte_eth_dev_configure(),
it can be enabled or disabled for individual queue in
ret_eth_[rt]x_queue_setup().
A new added offloading is the one which hasn't been enabled in
rte_eth_dev_configure() and is reuqested to be enabled in
rte_eth_[rt]x_queue_setup(), it must be per-queue type,
otherwise trigger an error log.
The underlying PMD must be aware that the requested offloadings
to PMD specific queue_setup() function only carries those
new added offloadings of per-queue type.

This patch can make above such checking in a common way in rte_ethdev
layer to avoid same checking in underlying PMD.

This patch assumes that all PMDs in 18.05-rc2 have already
converted to offload API defined in 17.11 . It also assumes
that all PMDs can return correct offloading capabilities
in rte_eth_dev_infos_get().

In the beginning of [rt]x_queue_setup() of underlying PMD,
add offloads = [rt]xconf->offloads |
dev->data->dev_conf.[rt]xmode.offloads; to keep same as offload API
defined in 17.11 to avoid upper application broken due to offload
API change.
PMD can use the info that input [rt]xconf->offloads only carry
the new added per-queue offloads to do some optimization or some
code change on base of this patch.

The vmxnet3 never attempts link speed negotiation.  As a virtual device
the link speed is vague at best.  However, it is important for certain
applications, like bonding, to see a consistent link_status.  802.3ad
requires that only links of the same cost (link speed) be enslaved.
Keeping the link status consistent in vmxnet3 avoids races with bonding
enslavement.

b7f6077374 net/vmxnet3: increase Rx data ring descriptor size
Vmxnet3 driver supports receive data ring viz. a set of small sized
buffers that are always mapped by the emulation. If a packet fits into
the receive data ring buffer, the emulation delivers the packet via the
receive data ring.

Increasing the receive data ring descriptor size from 128 to 256
showed performance gains as high as 5% for packets smaller than 256.

91f6191999 net/vmxnet3: fill imissed stat
This counter comes from a "hardware" register of the vmxnet3 device and
seems to behave like the MPC (Missed Packet Count) register of the Intel
NICs. So I think this data belongs in the imissed field rather than the
rx_nombuf field.

caccf8b318 ethdev: return diagnostic when setting MAC address
Change the prototype and the behavior of dev_ops->eth_mac_addr_set(): a
return code is added to notify the caller (librte_ether) if an error
occurred in the PMD.

The new default MAC address is now copied in dev->data->mac_addrs[0]
only if the operation is successful.

The patch also updates all the PMDs accordingly.

ffc905f3b8 ethdev: separate driver APIs
Create a rte_ethdev_driver.h file and move PMD specific APIs here.
Drivers updated to include this new header file.

There is no update in header content and since ethdev.h included by
ethdev_driver.h, nothing changed from driver point of view, only
logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.

More PMD specific data structures still remain in ethdev.h because of
inline functions in header use them. Those will be handled separately.

cebe3d7b3d ethdev: remove useless parameter in callback process
The pointer to the user parameter of the callback registration is
automatically pass to the callback function.
There is no point to allow changing this user parameter by a caller.
That's why this parameter is always set to NULL by PMDs and set only
in ethdev layer before calling the callback function.

The history is that the user parameter was initially used
by the callback implementation to pass some information
between the application and the driver:
	c1ceaf3ad0 ("ethdev: add an argument to internal callback function")
Then a new parameter has been added to leave the user parameter
to its standard usage of context given at registration:
	d6af1a13d7 ("ethdev: add return values to callback process API")

The NULL parameter in the internal callback processing function
is now removed. It makes clear that the callback parameter is user
managed and opaque from a DPDK point of view.

1e3a958f40 ethdev: fix link autonegotiation value
There are 3 kind of link data in ethdev:
	- capabilities (rte_eth_dev_info)
	- configuration (rte_eth_conf)
	- status (rte_eth_link)

A bit-field is used for capabilities (rte_eth_dev_info.speed_capa) and
configuration (rte_eth_conf.link_speeds).
Bits are defined in ETH_LINK_SPEED_*.

Some numerical (ETH_SPEED_NUM_*) and boolean (ETH_LINK_*) values
are used for the link status (rte_eth_link.*).

There was a mistake in the comment of rte_eth_link.link_autoneg,
suggesting ETH_LINK_SPEED_[AUTONEG/FIXED] which are 0/1,
instead of ETH_LINK_[AUTONEG/FIXED] which are 1/0.

The drivers are fixed to use ETH_LINK_[AUTONEG/FIXED].
