[dpdk-dev] [PATCH v5 0/2] bond: mode 4 support

[Michal Jastrzebski]

From: Pawel Wodkowski <pawelx.wodkowski at intel.com>

v2 changes:
New version handles race issues with setting/cancelin callbacks,
fixes promiscus mode setting in mode 4 and some other minor errors in mode 4
implementation.

v3 changes:
This is a rework of previous patchset. Basic functionality is the same but
contain following changes:
- use one global array of slaves instead separate instance for every bonded
  device (reduce memory usage). This also allow use of port id instead of
  offsetting to current active slaves.
- make mode 4 immune to partner timings standard violation.
- fix possible buffer overflow in RX function if caller provide buffer
  that is less than received packets (additional slow packets).
- change/fix promiscus mode and MAC management.
- fix compiling issues on gcc version less than 4.5
- bring API for tunig mode 4 parameters and expose mode 4 frames structure.
- prevent console flood with warning messages if mode 4 RX/TX buffers are full.

test-pmd:
- add mode 4 support (force periodic TX if no packets received during 100ms
  period). Some forwardning modes (ex. rx only) does not allow mode 4 usage.
- 'port start X' - check if X is valid value

changes not related to mode 4:
- fix memcpy() usage in bond_ethdev_tx_burst_balance() (OOM/undfined behaviour
  if TX burst fail)

v4 changes:
- fix compilation error when building without mbuf refcnt
- testpmd: add slave state information in "show bonding config X" command
- change patch dependency to Declan Doherty v6

v5 changes
- fix compilation errors when CONFIG_RTE_LIBRTE_PMD_BOND=n

Those patches depend from Declan Doherty v8 patchset and rte alarm patches.
