Re: [dts] [PATCH V1]tests/runtime_queue_number: fix the issue ofcreating VF on eagle in two ports

["Tu, Lijuan" <lijuan.tu@intel.com>]

ixgbe, each pf has 128 queues at most, pf and it's vfs share these queues.
如果vf个数大于8，每个vf最多16个queue，如果vf个数大于16，每个vf最多8个queue，如果vf个数大于32，每个vf最多4个queue，以此类推，pf 就用vf用完了后剩下的queue。

There can be set 128 vfs per Fortville card.
If there are 4 10G port in one fvl card, each port can be set 32 vfs.
The whole number of queue per NIC is 1536.
So if there are 4 ports, there are 384 queues per port, which are shared by pf and vfs.


根据这个把hard code 改掉，先评估下难度和时间。
