I haven't investigated that specially to recommend something as most of
my cards are integrated, but now I have newer systems with:
em0 at pci13:0:0: class=0x020000 card=0x108c15d9 chip=0x108c8086 rev=0x03
hdr=0x00
vendor = 'Intel Corporation'
device = '82573E Intel Corporation 82573E Gigabit Ethernet
Controller (Copper)'
class = network
subclass = ethernet
cap 01[c8] = powerspec 2 supports D0 D3 current D0
cap 05[d0] = MSI supports 1 message, 64 bit enabled with 1 message
cap 10[e0] = PCI-Express 1 endpoint
and older systems with:
em0 at pci2:10:0: class=0x020000 card=0x12138086 chip=0x10138086 rev=0x00
hdr=0x00
vendor = 'Intel Corporation'
device = '82541EI Gigabit Ethernet Controller (Copper)'
class = network
subclass = ethernet
cap 01[dc] = powerspec 2 supports D0 D3 current D0
cap 07[e4] = PCI-X supports 2048 burst read, 1 split transaction
I can't compare load directly now as load is different, but I have
noticed benefits after replacing old systems with new ones. General
recommendation is usual: newer is usually better. :)
