What driver/NIC is using cxgb feature/s?

[Won]

Hello,

I am just curious what driver/NIC is using cxgb msi tunable. I don't have a Chelsio NIC installed on the box.

#  sysctl -a | grep msi
hw.bce.msi_enable: 1
hw.cxgb.msi_allowed: 2
hw.pci.honor_msi_blacklist: 1
hw.pci.enable_msix: 1
hw.pci.enable_msi: 1


Some relevant info:

cxgb is using it.

: #  sysctl -a | grep msi
: hw.bce.msi_enable: 1
: hw.cxgb.msi_allowed: 2
: hw.pci.honor_msi_blacklist: 1
: hw.pci.enable_msix: 1
: hw.pci.enable_msi: 1

This just means that if you had a cxgb device, the hints are
suggesting you use it.  If you don't have one, then nothing will
happen.  You get this because you have cxgb compiled into the kernel,
or loaded as a module.
