vmxnet3 driver supports transmit data ring viz. a set of fixed size
buffers used by the driver to copy packet headers. Small packets that
fit these buffers are copied into these buffers entirely.
Currently this buffer size of fixed at 128 bytes. This patch extends
transmit data ring implementation to allow variable length transmit
data ring buffers. The length of the buffer is read from the emulation
during initialization.

Shared memory is used to exchange information between the vmxnet3 driver
and the emulation. In order to request emulation to perform a task, the
driver first populates specific fields in this shared memory and then
issues corresponding command by writing to the command register(CMD). The
layout of the shared memory was defined by vmxnet3 version 1 and cannot
be extended for every new command without breaking backward compatibility.
To address this problem, in vmxnet3 version 3, the emulation repurposed
a reserved field in the shared memory to represent command information
instead. For new commands, the driver first populates the command
information field in the shared memory and then issues the command. The
emulation interprets the data written to the command information
depending on the type of the command. This patch exposes this capability
to the driver.

During PF initialization, PF will generate an initial mac address
for VFs, the purpose is to help VF keep a constant mac address between
its startup/shutdown cycles. Now this is not necessary, since we already
provide an API to set VF's MAC address from PF side
(rte_pmd_i40e_set_vf_mac_addr).
Application can use this API to lock down VF's mac address.(of course this
should happen before VF init)
While without this patch, we still can use rte_pmd_i40e_set_vf_mac_addr
to overwrite the random one, but this patch align DPDK's default behavior
with Kernel PF driver's, and this help to give an identical experience
when work with kernel VF driver.
