Re: [dpdk-dev] [PATCH 2/2] i40e: Enlarge the number of supported queues

["Zhang, Helin" <helin.zhang@intel.com>]

Hi David

PF, VFs VMDq, FD on the same port share the queues, actually we can know the total number of the queues, the maximum number of queues may vary depends on how they will be used with PF, VF, VMDq AND FD.
So the users will define the number for each, the code will just check the total number of them and make sure not exceed that.

Regards,
Helin

Note: just resend it with plain text format.

It enlarges the number of supported queues to hardware allowed

which is not reasonable.

I looked at the commit that introduced this limitation, can't we just get rid of this ?
The primary process should know the current max queue number and initialises the array properly before any secondary process tries to set any callback, or tries to call rx/tx functions.
Did I miss something ?
