In counterpoint, my build machine for the last few years has been a Dell
mini-tower I bought from Costco... with its original disk drive removed
(replaced by an SSD, then supplemented with 3 more for a poudriere
scratch-space). It runs a GENERIC kernel, tracking stable/11 & head
daily, using poudriere to build local packages weekly, and acting as an
NFS server for my "production" machines for their weekly updates.
Its NIC:
re0@pci0:3:0:0: class=3D0x020000 card=3D0x05b71028 chip=3D0x816810ec rev=3D=
0x0c hdr=3D0x00
vendor =3D 'Realtek Semiconductor Co., Ltd.'
device =3D 'RTL8111/8168/8411 PCI Express Gigabit Ethernet Controll=
er'
class =3D network
subclass =3D ethernet

(It is connected to a "dumb" 16-port Netgear gigabit switch.)
I will admit that I avoid having the machine try to do too much
else while the production machines are using it as an NFS server
(serving /usr/src & /usr/obj, while (e.g.) "make installworld" runs
on the production machines), but other than that, I have no issues
involving performance and behavior of the NIC and its driver.
Peace,

Well, what did you EXPECT from Trump? He has a history of breaking promise=
