35 .Nd Broadcom BCM570x family Gigabit Ethernet driver
37 .Cd "bge* at pci? dev ? function ?"
39 Configuration of PHYs may also be necessary.
45 device driver supports Gigabit Ethernet interfaces based on the Broadcom
46 BCM570x family of Gigabit Ethernet chips and the BCM5906 chip.
47 The interfaces supported by the
52 3Com 3c996-T (10BASE-T/100BASE-TX/1000BASE-T)
54 Dell PowerEdge 2550 integrated BCM5700 NIC (10BASE-T/100BASE-TX/1000BASE-T)
56 IBM x235 server integrated BCM5703x NIC (10BASE-T/100BASE-TX/1000BASE-T)
58 Netgear GA302T (10BASE-T/100BASE-TX/1000BASE-T)
60 SysKonnect SK-9D21 (10BASE-T/100BASE-TX/1000BASE-T)
62 SysKonnect SK-9D41 (1000BASE-SX)
65 The BCM570x family supports IPv4/TCP/UDP checksumming in hardware.
68 driver supports this feature of the chip.
71 for information on how to enable this feature.
73 The level of interrupt mitigation for received packets can be adjusted
80 interrrupt for every two full-sized Ethernet frames.
81 Each increment of the value will, roughly, halve receive interrupt rate,
82 up to a maximum of 5, which interrupts about every 30 to 40 full-sized
