[f-nsp] Packet loss on MLXe-4

[Frank Bulk]

We inserted an MLXe-4 into a Brocade ring this morning and it didn't go so
well.  We saw most IP video traffic (1.3 Gbps) not flow through, and when we
moved an inter-border router link from eth 1/2 to eth 2/2 we saw significant
packet loss on other Internet VLANs (all on eth 1/x).  Moving it back
resolved the issue.

We have two SFMs and have two four-port 10G cards, one is a NI-XMR-10Gx4 and
the other is a BR-MLX-10Gx4-X.  We also have a BR-MLX-1GCx24-X in slot 3
that we're not using, yet.  We're running 5.4.0d and the FPGAs are at the
correct releases.

The ring goes in one 10G port on the one 10G card and through another 10G
port on the other 10G card.

Are there any compatibility issues between the two cards?  Placement
requirements?  Any obvious reasons why we experienced all that traffic loss?

Frank
