Enable the Link Alarm Status Interrupt (LASI) only for X552 devices
to receive notifications of the link configurations of the external
PHY and correspondingly support the configuration of the internal
iXFI link, since iXFI does not support auto-negotiation.
This is not required for X553 devices having KR support, which
performs auto-negotiations and which is used as the internal
link to the external PHY.

Previous reported speed was hardcoded because there was not firmware
support for getting this information. This change needs also to support
old firmware versions, but instead of the previous hardcoded report, no
speed is reported to the user avoiding to give the wrong speed when link
is not configured to 40G.

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.
