net/vmxnet3: fix Rx deadlock

Our use case is that we have an app that needs to keep mbufs around
for a while. We've seen cases when calling vmxnet3_post_rx_bufs() from
vmxet3_recv_pkts(), it might not succeed to add any mbufs to any RX
descriptors (where it returns -err). Since there are no mbufs that the
virtual hardware can use, no packets will be received after this; the
driver won't refill the mbuf after this so it gets stuck in this
state. I call this a deadlock for lack of a better term - the virtual
HW waits for free mbufs, while the app waits for the hardware to
notify it for data (by flipping the generation bit on the used Rx
descriptors). Note that after this, the app can't recover.

This fix is a rework of this patch by Marco Lee:
http://dpdk.org/dev/patchwork/patch/6575/. I had to forward port
it, address review comments and also reverted the allocation
failure handling to the first version of the patch
(http://dpdk.org/ml/archives/dev/2015-July/022079.html), since
that's the only approach that seems to work, and seems to be what
other drivers are doing (I checked ixgbe and em). Reusing the mbuf
that's getting passed to the application doesn't seem to make
sense, and it was causing weird issues in our app. Also, reusing
rxm without checking if it's NULL could cause the code to crash.

net/i40e/base: fix unknown PHYs incorrect identification

The PHY type value for unrecognized PHYs and cables was changed
based on firmware version number. Newer hardware use lower firmware
version numbers and this was causing some PHYs to be identified
as type 0x16 instead of 0xe (unknown).

Without this patch, newer card will incorrectly identify unknown
PHYs and cables.

This change adds hardware type to the check for firmware version
so the PHY type is reported correctly.

This problem is fixed by changing how often we update link
