Yes, i tried, but have no effect.

after reboot interface works, but if i try to ping with packet for
example 1500 bytes and interval 0.01s it looks like

What about other NIC chips from Broadcom? And how about the packets other
than icmp under the same load?

There are different types of broadcom chips on my hardware:

bge0: <Broadcom BCM5721 Gigabit Ethernet, ASIC rev. 0x4101>
mem 0xddef0000-0xddefffff irq 16 at device 0.0 on pci5
miibus0: <MII bus> on bge0
brgphy0: <BCM5750 10/100/1000baseTX PHY> on miibus0
brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX, 1000baseTX-FDX, auto
bge0: Ethernet address: 00:15:f2:cd:21:9a

I don't have any other type of broadcom NIC to test but all other
NICs, for example Intel works correctly.

p.s. MB: ASUSTeK P5M2 /2GBL
