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 i 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)
Those patches depend from Declan Doherty v5 (rebased to be aplicable on top of
commit b6583ee402656ea86c8a3b92e009a99e13726781) patchset and rte alarm patches.

Michal, if you worked on this patch you should add your signed-off-by.
I think it would be a good idea to briefly describe the bonding mode 4
in the commit log.
Thanks

Hi Thomas,
No I didn't work on this patch. I will prepare a description for bonding mode 4.

I temporary lost ability to use git send-email command so I asked Michal

Since Declan sent a v6 for link bonding changes, maybe it is a good idea
to send another version, as v5 will not be merged.

Hi Pablo
I compared v6 patches vs patches produced by git rebase v5 patches
on top which I used to produce mode 4 v3 patches and I think they are
compatible. There is one difference is in unit tests but, fortunately I
do not touch unit tests yet so they are be applicable. I can't fully verify
that as I am unable to apply patches in v6.
If you think this is insufficient perhaps I should wait for Declan's patches
be merged into master branch.

Ok, I did manage to apply v6 patches after pulling latest commits. Mode 4
patches are applicable also for Declan's v6 patches.

I just checked it and it applied fine, but there is a tiny problem.
If you disable CONFIG_RTE_MBUF_REFCNT, then it hides the implementation of
bond_ethdev_tx_burst_8023ad, and then you get a compilation error.
It is solved by just moving the condition #ifdef RTE_MBUF_REFCNT after your function,
but still this will probably need another version or maybe a patch after.
Thanks,
Pablo
