1f693b8f37 ethdev: remove useless parameter in init functions
The pointer to struct eth_driver is not used and is already set
in struct rte_eth_dev.

It's a small cleanup in PMD API which probably needs more
attention to make clear what is a driver, a PCI driver, an
ethernet driver, etc.

b12964f621 ethdev: unification of RSS offload types
RSS offload types were defined separately for 1/10G and 40G NICs,
and have no relationship with flow types. The modifications are to
unify all RSS offload types for all PMDs. Unified RSS offload types
have new and common names which can be used for any PMD or
applications, and decouple from specific hardwares.

494a1f991e ixgbevf: fix link state
This patch fixes checking the link state of a virtual function. If the
state has already been checked, it does not need to be checked
again. Previously, get_link_status in the ixgbe_hw struct was used to
track if the information had already been retrieved, but this field
was always set to false (signifying that the information was
up-to-date). The problem was introduced by commit 8ef32003 which was
part of a patch set to update the ixgbe portion of the PMD. This patch
does not break consistency with the ixgbevf driver. Instead, it fixes
the problem at the level of DPDK.

Applications that rely on the reported link speed could fail without
this patch. The qos_sched example application provided with DPDK did
not run when virtual functions were used. The output for this example
application is shown below:

EAL: Error - exiting with code: 1
  Cause: Unable to config sched subport 0, err=-2

The problem and the effect of the patch can been seen by running the
l2fwd example application using the following command:

sudo ./build/l2fwd -c 0x3 -n 4 -- -p 0x3 -T 0

Before the patch has been applied (with both links up):
...

Port 0 Link Up - speed 100 Mbps - half-duplex

Port 1 Link Up - speed 100 Mbps - half-duplex

L2FWD: entering main loop on lcore 1

Root cause is test app on primary process only starts device, but

46bc9d7513 ixgbe: fix multi-process support
When using multiple processes, the TX function used in all processes
should be the same, otherwise the secondary processes cannot transmit
more than tx-ring-size - 1 packets.
To achieve this, we extract out the code to select the ixgbe TX function
to be used into a separate function inside the ixgbe driver, and call
that from a secondary process when it is attaching to an
already-configured NIC.

Testing with symmetric MP app shows that we are able to RX and TX from
both primary and secondary processes once this patch is applied.

1224decaa4 ixgbe: support TCP segmentation offload
Implement TSO (TCP segmentation offload) in ixgbe driver. The driver is
now able to use PKT_TX_TCP_SEG mbuf flag and mbuf hardware offload infos
(l2_len, l3_len, l4_len, tso_segsz) to configure the hardware support of
TCP segmentation.

In ixgbe, when doing TSO, the IP length must not be included in the TCP
pseudo header checksum. A new function ixgbe_fix_tcp_phdr_cksum() is
used to fix the pseudo header checksum of the packet before giving it to
the hardware.

In the patch, the tx_desc_cksum_flags_to_olinfo() and
tx_desc_ol_flags_to_cmdtype() functions have been reworked to make them
clearer. This should not impact performance as gcc (version 4.8 in my
case) is smart enough to convert the tests into a code that does not
contain any branch instruction.

66c594904a ethdev: support multiple sizes of redirection table
As 40G NIC supports different sizes (128/512/64 entries) of
redirection table from that (128 entries) of 1G and 10G NICs,
support of multiple sizes of redirection table is needed.
It includes,
* Redefine 'struct rte_eth_rss_reta' in ethdev.
  - To 'struct rte_eth_rss_reta_entry64' which contains 64
    entries and 64 bits mask.
  - Array of above new structure can be used for any number of
    redirection table entries, as long as the number is multiple
    of 64. This is quite flexible for the future expanding of
    redirection table.
* Redefinition of relevant interfaces in ethdev.
  - Interface of reta update has been redefined with new parameters.
  - Interface of reta query has been redefined with new parameters.
* Rework of 1G PMD in igb.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 10G PMD in ixgbe.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 40G PMD (PF only) in i40e.
  - reta update has been reworked.
  - reta query has been reworked.
* Implement relevant commands in testpmd.

16321de093 ethdev: allow to get RSS hash functions and key
1) Add a new function "rss_hash_conf_get" in the PMD API to retrieve the
   current configuration of the RSS functions and/or of the RSS key used
   by a NIC to compute the RSS hash of input packets.
   The new function uses the existing data structure "rte_eth_rss_conf" for
   returning the RSS hash configuration.

2) Add the ixgbe-specific function "ixgbe_dev_rss_hash_conf_get" and the
   igb-specific function "eth_igb_rss_hash_conf_get" to retrieve the RSS
   hash configuration of ixgbe and igb controllers respectively.

3) Add the command "show port X rss-hash [key]" in the testpmd application
   to display the RSS hash configuration of port X.

db5b65301d ethdev: allow to set RSS hash computation flags and/or key
1) Add a new function "rss_hash_update" in the PMD API to dynamically
   update the RSS flags and/or the RSS key used by a NIC to compute the RSS
   hash of input packets.
   The new function uses the existing data structure "rte_eth_rss_conf" for
   the argument that contains the new hash flags and/or the new hash key to
   use.

2) Add the ixgbe-specific function "ixgbe_dev_rss_hash_update" and the
   igb-specific function "eth_igb_rss_hash_update" to update the RSS
   hash configuration of ixgbe and igb controllers respectively.
   Before changing anything, these 2 functions check that the update RSS
   operation does not attempt to disable RSS, if RSS was enabled at port
   initialization time, or does not attempt to enable RSS, if RSS was
   disabled at port initialization time.

Note:
   Configuring the RSS hash flags and the RSS key used by a NIC consists in
   updating appropriate PCI registers of the NIC.
   These operations have been manually tested with the interactive commands
   "write reg" and "write regbit" of the testpmd application.

0e57cebf74 ixgbevf: assign a default mac address
When initializing a VF with no initial MAC address assigned by
the underlying Host PF driver, assign a default MAC address.

b6562244b4 ixgbevf: skip null and permanent mac addresses
On a 82599 VF, the deletion of a dynamically added MAC address consists in
first flushing all added MAC addresses, then in adding again all remaining MAC
addresses.
For this purpose, the function ixgbevf_remove_mac_addr() parses the pool
of MAC addresses associated with a VF, and must skip the VF permanent MAC
address that is stored into it, as well as all NULL MAC addresses.

7bfd68a274 ixgbevf: avoid adding twice the permanent mac address
During the initialization of a VF device, the rte_eth_dev_start() function
indirectly invokes the PMD "mac_addr_add" function with the permanent MAC
address assigned to the device.
In the case of 82599 VFs, this operation leads to exhausting the very
limited set of PF resources used to store VF MAC addresses.

To address this issue, do nothing in the function ixgbevf_add_mac_addr()
if the added MAC address is equal to the permanent MAC address of the VF.

17d32e45d5 ixgbevf: add/remove mac address
Add missing PMD functions in the ixgbevf driver to add (respectively remove)
a MAC address to/from a 82599 VF.
For this purpose, these 2 functions use the VF/PF mailbox-based protocol.

88fccb7a05 ixgbevf: fix jumbo frame
When latest Linux ixgbe PF is used, and DPDK VF is used in DPDK application,
jumbo frames are not received.
Also - if Linux ixgbe PF has MTU set to 1500 (default),
then normal sized packets can be received by DPDK VF.
However, if Linux PF has MTU > 1500, then DPDK VF receives no packets
(normal or jumbo).
With ixgbe_mbox_api_10 ixgbe simply didn't allow set VF MTU > 1514 for 82599.
With ixgbe_mbox_ajpi_11 it does, though now, if PF uses jumbo frames,
it simply disables RX for all VFs.
So to work with PF ithat using jumbo frames, at startup each VF has to:
1. negotiate with PF mbox_api_11.
2. Send to PF SET_LPE message with desired MTU.
Note, that if PF already uses MTU bigger then asked by the VF,
then PF wouldn't take any action.
