A DCF (Device Config Function) based approach is proposed where a device
bound to the device's VF0 can act as a sole controlling entity to exercise
advance functionality (such as switch, ACL) for rest of the VFs.
The DCF works as a standalone PMD to support this function, which shares the
ice PMD flow control core function and the iavf virtchnl mailbox core module.
v6:
No change, but to resend the same patchset again to trigger
ci/Performance-Testing
by using the new code base:
https://lab.dpdk.org/results/dashboard/patchsets/10120/
v5:
Fixed the shared module compile errror.
v4:
Change the alarm handler to thread service, since it will need to do more
work.
v3:
1. Fixed the error log message format.
2. Fixed some memory allocation check.
3. Fixed some code style issue and commmit message description.
v2:
1. update the iavf patchset link.
2. split more patches for making this work be more understandable
3. fix the log function usage, devargs checking from v1.
Haiyue Wang (7):
net/iavf: stop the PCI probe in DCF mode
net/ice: add the DCF hardware initialization
net/ice: acquire and disable the DCF capability
net/ice: handle the AdminQ command by DCF
net/ice: export the DDP definition symbols
net/ice: handle the PF initialization by DCF
net/ice: get the VF hardware index in DCF
