>Description:
Fujitsu PRIMERGY RX200 has two LAN interfaces detected as wm0 and wm1.
wm0 can not receieve arp request from other hosts, but wm1 can receive.

The interfaces is detected as follows:

wm0 at pci2 dev 2 function 0: Intel i82546EB 1000BASE-T Ethernet, rev.1
wm0: interrupting at ioapic2 pin 0 (irq 10)
wm0: 64-bit 100MHz PCIX bus
wm0: 256 word (8 address bits) MicroWire EEPROM
wm0: Ethernet address 00:14:85:07:04:80
makphy0 at wm0 phy 1: Marvell 88E1011 Gigabit PHY, rev. 3
makphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 
1000baseT-FDX, auto
wm1 at pci2 dev 2 function 1: Intel i82546EB 1000BASE-T Ethernet, rev. 1
wm1: interrupting at ioapic2 pin 1 (irq 10)
wm1: 64-bit 100MHz PCIX bus
wm1: 256 word (8 address bits) MicroWire EEPROM
wm1: Ethernet address 00:14:85:07:04:81
makphy1 at wm1 phy 1: Marvell 88E1011 Gigabit PHY, rev. 3
makphy1: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 
1000baseT-FDX, auto

This behavior is shown on NetBSD 3.0, too.
But this machine is no problem with other OS (ex. FreeBSD, Linux).
