v8 cover remove pci driver from vdevs

In reply to a message not in the archive

There is a dummy pci driver in the vdev PMD's at present.
This patch set removes the pci driver from the vdev PMD's.
Changes have been made to librte_ether to handle vdevs and pdevs in the same way.

The following vdev PMD's have had the pci driver removed:

null
ring
bonding
pcap
af_packet
xenvirt
mpipe

All the pdev PMD's have been modified to copy the pci device info into eth_dev data.

Changes in v8:
rebase
changes to librte patch in response to comments
changes to bonding patch in response to comments
squashed pdev copy device info patches
squashed vdev copy device info patches

Changes in v7:
rebase to latest code.

Changes in v6:
Initialise data->drv_name with the PMD driver name in the vdevs. Remove two more branches on pci_dev from the bonding vdev.

Changes in v5:
rebase to latest code.
refactor patches to avoid potential problems with git bisect.

Changes in v4:
rebase to latest code.
add doxygen comments to rte_ethdev.h
update release notes in patch 0002.

Changes in v3:
rebase to latest code.
restructure patches 0002 and 0003 to fix compile issue in patch 0002.

Changes in V2:
rebase to latest code.
fix compile error in rte_ethdev.c when debug disabled.
remove Intel copyright from bnx2x, cxgbe, enic, mlx4, mpipe and null PMD's.

Bernard Iremonger (11):
librte_ether: add fields from rte_pci_driver to rte_eth_dev_data

PATCH v8 1/11 librte_ether: add fields from rte_pci_driver to rte_eth_dev_data

The driver fields have been added the rte_eth_dev_data so that it is no longer necessary access this data through the pci_dev pointer.

The following fields have been added to rte_eth_dev_data:

dev_flags, and macros for dev_flags.
kdrv
numa_node
drv_name

add function rte_eth_copy_pci_info
remove branches on pci_dev

librte_eal: add RTE_KDRV_NONE for vdevs

PATCH v8 11/11 bonding: remove pci device

In reply to Bernard Iremonger

remove pci_dev, pci_drv, rte_bond_pmd and pci_id_table. handle numa_node for vdevs
handle RTE_ETH_DEV_INTR_LSC for vdevs
rename the function valid_bonded_device to check_for_bonded_device remove branches on pci_dev

Re: [PATCH v8 03/11] vdev: copy device info to eth_dev data

Below, a lot of pci values are removed and break the build. Will move in later patches.

There is a dummy pci driver in the vdev PMD's at present.
This patch set removes the pci driver from the vdev PMD's.
Changes have been made to librte_ether to handle vdevs and pdevs in the same way.

Applied with some fixes, thanks
