[dpdk-dev] [PATCH v2 2/3] fm10k: remove mbuf size sanity check

From: "Chen Jing D(Mark)" <jing.d.chen at intel.com>
Original implementation required mbuf size should be greater than
ETHER_MAX_VLAN_FRAME_LEN, which is not necessary. If it's less
than that value, scatter function will be selected and incoming
packets greater than mbuf size will be filled into several mbufs.
