I've a handful of 1550s as well. None of them exhibit any problems
speaking to the network as connected to Netgear 10/100 switches (well,
one did at one time, but it turned out to be a motherboard hardware
fault). One of the servers' sole duty is to take backups of various
large files on other machines on the LAN and it works just fine.
Here's the pciconf output from that 'backup' machine:
fxp0@pci0:1:0: class=0x020000 card=0x00da1028 chip=0x12298086 rev=0x08 hdr=0x00
vendor = 'Intel Corporation'
device = '82557/8/9 EtherExpress PRO/100(B) Ethernet Adapter'
class = network
subclass = ethernet
fxp1@pci0:2:0: class=0x020000 card=0x00da1028 chip=0x12298086 rev=0x08 hdr=0x00
vendor = 'Intel Corporation'
device = '82557/8/9 EtherExpress PRO/100(B) Ethernet Adapter'
class = network
subclass = ethernet
uname -r: 4.8-RELEASE-p3
I wouldn't rule out hardware. The Dell diagnostics are amazingly good
at finding hardware faults. It could just as well be your switch/hub.
I have an old 5-port hub that none of my fxp ports will speak to, but
the de and sis ones do.
