[dpdk-dev] [PATCH v2 0/2] ethdev: add port speed capability bitmap

[Marc Sune]

The current rte_eth_dev_info abstraction does not provide any mechanism to
get the supported speed(s) of an ethdev.

For some drivers (e.g. ixgbe), an educated guess can be done based on the
driver's name (driver_name in rte_eth_dev_info), see:

http://dpdk.org/ml/archives/dev/2013-August/000412.html

However, i) doing string comparisons is annoying, and can silently
break existing applications if PMDs change their names ii) it does not
provide all the supported capabilities of the ethdev iii) for some drivers it
is impossible determine correctly the (max) speed by the application
(e.g. in i40, distinguish between XL710 and X710).

This small patch adds speed_capa bitmap in rte_eth_dev_info, which is filled
by the PMDs according to the physical device capabilities.

v2: rebase, converted speed_capa into 32 bits bitmap, fixed alignment
(checkpatch).

  Added ETH_SPEED_CAP bitmap in rte_eth_dev_info
  Filling speed capability bitmaps in the PMDs
