Ethernet device 37.Sh SYNOPSIS 38.Cd "em* at pci?" 39.Sh DESCRIPTION 40The 41.Nm 42driver provides support for PCI, PCI-X and PCI Express Gigabit Ethernet adapters 43based on the Intel 82540EM, 82540EP, 82541EI, 82541ER, 82541GI, 82541PI, 82542, 4482543GC, 82544EI, 82544GC, 82545EM, 82545GM, 82546EB, 82546GB, 82547EI, 82547GI, 4582562V, 82563EB, 82564EB, 82566DC, 82566DM, 82571EB, 82571GB, 82572EI, 82572GI, 4682573E, 82573L and 4782573V Ethernet controller chips. 48The driver supports IPv4 receive IP/TCP/UDP checksum offload on all but 4982542-based adapters and Jumbo frames on all but 82562V, 82566DC/82566DM and 5082573E/82573L/82573V-based adapters. 51The 82562V Ethernet controller chip only supports 10/100 media types. 52This includes the following models: 53.Pp 54.Bl -item
