According to the tests that I was doing, the CONFIG_FIRMWARE_IN_KERNEL=y
option is not sufficient. Also it is necessary to use CONFIG_BNX2=y.

According to which I was reading, with the CONFIG_FIRMWARE_IN_KERNEL=y
option, the driver is including in kernel as long as driver it is
compiled in kernel and not in modular form. In order to obtain this it
is necessary to use the CONFIG_BNX2=y option. This option is established
following the path Device Drivers -> Network device support -> Ethernet
(1000 Mbit) of the ncurses menu. Then, we marked with asterisk Broadcom
NetXtremeII support here.

With this, the interfaces were configured during bootstrapping without
problems:

Thanks for your reply.
