NAME

     vte -- Vortex86 RDC R6040 Fast Ethernet driver

SYNOPSIS

     vte* at pci? dev ? function ?

     Configuration of PHYs is necessary.  See rdcphy(4).

DESCRIPTION

     The vte device driver provides support for RDC R6040 Fast Ethernet controller which is commonly found on Vortex86 System On a Chip (SoC).

     The RDC R6040 has integrated 10/100 PHY for 10/100Mbps support in full or half-duplex.  The controller supports interrupt moderation mecha-
     nism, a 64-bit multicast hash filter, VLAN over-size frame and four station addresses.  The vte device driver uses three station addresses
     out of four as perfect multicast filter.

SYSCTL VARIABLES

     The following variables are available

     hw.vte.vte<x>.int_rxct
	     Maximum number of packets to fire RX completion interrupt.  The accepted range is 0 (disable interrupt moderation) to 15, the default
	     is 0.

     hw.vte.vte<x>.int_txct
	     Maximum number of packets to fire TX completion interrupt.  The accepted range is 0 (disable interrupt moderation) to 15, the default
	     is 0.

HISTORY

     The vte driver was written for FreeBSD by Pyun YongHyeon <yongari@FreeBSD.org> and ported to NetBSD by Manuel Bouyer <bouyer@NetBSD.org>.
     The vte device driver first appeared in NetBSD 6.0.

NAME

     jme -- JMicron Technologies JMC250 Gigabit Ethernet and JMC260 Fast Ethernet controller driver

SYNOPSIS

     jme* at pci? dev ? function ?

     Configuration of PHYs is necessary.  See mii(4).

DESCRIPTION

     The 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:

     hw.jme.jme<x>.int_rxtos  jme receive interrupt moderation timer, in microseconds (defaults to 100)

     hw.jme.jme<x>.int_rxct   jme receive interrupt moderation packet counter (defaults to 128)

     hw.jme.jme<x>.int_txto   jme transmit interrupt moderation timer, in microseconds (defaults to 100)

     hw.jme.jme<x>.int_txct   jme transmit interrupt moderation packet counter (defaults to 128)

SEE ALSO

     ifmedia(4), mii(4), netintro(4), pci(4), ifconfig(8)

HISTORY

     The jme device driver first appeared in NetBSD 5.0.

BUGS

     Hardware bugs prevent support of IPv6 receive TCP/UDP checksum offload in the JMC250 rev A2, and is disabled in the driver.  This should be
     revisited when a newer hardware revision is available.
