This is caused by c99d667e8527 ("cnic : Cleanup CONFIG_IPV6 & VLAN check")
So I'm not really sure what the fix for this is. CNIC will properly only support [m] or [n] when IPV6 is compiled as a module, but if you set SCSI_BNX2X_FCOE or SCSI_BNX2_ISCSI to be in built, there is a 'select CNIC' that forces CNIC to be inbuilt, even though this is not supported by Kconfig. I was under the assumption that select will not forcibly change m to inbuilt (or perhaps I'm missing some syntax suboption ?)
This is still fixable in SCSI_BNX2_ISCSI using the same logic used in the above mentioned commit, but not so in SCSI_BNX2X_FCOE where it causes a recursive dependency error (thought it is fixing the issue nevertheless), and none of the other solutions I tried seemed to work either.
Looking at previous code, the earlier approach used to just disable ipv6 code in such a situation. -Anish

Building with the attached random configuration file,
