Card PCIe NC375T not recognized

[Samuel REMOUE]

(Sorry for my english) Hello,
I'm new on FreeBSD OS and am trying to deploy servers.
I have a concern: HP NC375T NIC (HP NC375T PCI Express Quad Port
Gigabit Server Adapter) is not recognized, the drivers from HP are
available here (http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=4038767&lang=fr&cc=fr&prodTypeId=329290&prodSeriesId=4038765&taskId=135).
This is a QLogic / NetXen NX3031-based card.
If possible, can someone give me the steps to follow to integrate
drivers that are suitable into my install ? Thank you in advance.
