Message-ID: <1248191267.18195.50.camel@lb-tlvb-eilong>

Subject: [net-next 7/10] bnx2x: Supporting BCM8727 PHY
Adding support for BCM8727 - a dual port SFP+ PHY. That includes verification of
the optic module vendor and part number - the list of approved modules resides
on the nvram and the module is verified by the FW. Since not all users would
like to use this verification feature, it can be disabled. The default behavior
is to issue a warning if the module is not approved, but still allow using it -
but it is also possible to disable the link if the module is not approved.
