Re: [dpdk-dev] [PATCH 0/2] Mellanox ConnectX-3 PMD

[Keunhong Lee <dlrmsghd@gmail.com>]

How fast does this driver perform?
Is it capable for sending/receiving 64B packets at 40G line rate?
I'm using another version of user driver and it is not scalable for line
rate, regardless of the number of TX cores.
