jme —
jme* at pci? dev ? function ?
Configuration of PHYs is necessary. See mii(4).
jme device driver supports network adapters based on
the JMicron Technologies JMC250 Gigabit Ethernet and JMC260 Fast Ethernet
chips. The following features are supported:
IPv4 transmit/receive IP/TCP/UDP checksum offload IPv6 transmit TCP/UDP checksum offload IPv4 and IPv6 TCP segmentation offload VLAN tag insertion/removal Interrupt coalescing 10/100/1000Mbps operation in full-duplex mode 10/100Mbps operation in half-duplex mode Jumbo frames (up to 9022 bytes)
Due to hardware limitation checksums and TCP segmentation offload can't be enabled if the configured MTU is larger than 4000 bytes.
Interrupt coalescing can be controlled on a per-adapter basis through the following sysctls:
