Why installation of a new kernel package on Red Hat Enterprise Linux 6 install bfa-firmware package as dependency ?

Issue

• Why does the installation of a new kernel package on Red Hat Enterprise Linux 6 install bfa-firmware package as dependency even if the system does not have a Brocade Fibre Channel HBA ?
  Eg:

# lspci |grep -i HBA

# grep -i HBA /var/log/dmesg

# yum install kernel
