Hello, guys! Please, can someone point a NIC, PCI 2.2 specs, full VLAN capable under FreeBSD? I?m finding terrible issues using RTL8169 and 3C9x, almost all for the fact NIC cannot handle MTU a little bigger than 1500 (1500 + vlan tagging). I don?t wish reducing MTU. -- Edvaldo Silva - Administrador de Redes Americana Digital www.americanadigital.com.br (19) 3471-2000

I've used them for a long time in servers, but now they average around $3 in quantity on eBay and I use them in everything. Also, many off-lease PC's come with it on the motherboard. For GigE, I prefer (also) Intel Etherexpress --- but the driver is "em" (I have not tried "igb). I also have had no complaints with "bge" and "bce" driver chipsets on equipped motherboards. In both cases, I make heavy use of vlans and hardware vlan tagging. Many router machines have between 10 and 50 vlan interfaces.

The Intel ones driven by em(4) (Intel EtherExpress Pro/1000)? RTL8169/8111/8168 use closed specs, quirks have to be reverse engineered into the driver.

I'm using bge(4) and bce(4) interfaces (Broadcom GBit) and
fxp(4) ones (100 MBit) in enviroments with heavy use of VLANs.
They work very well. There are no problems with the MTU.
Best regards
