Following the docs on creating VLANs on an Intel i218 NIC: https://www.freebsd.org/doc/handbook/network-vlan.html (with different IP addresses) produces a very slow network on both the non-VLAN and VLAN interfaces. Trying to then destroy the VLAN interface then results in ifconfig and the non-VLAN network interface hanging. Details on the NIC in question: em0@pci0:0:25:0: class=0x020000 card=0x85c41043 chip=0x15a18086 rev=0x05 hdr=0x00 vendor = 'Intel Corporation' device = 'Ethernet Connection (2) I218-V' class = network subclass = ethernet bar [10] = type Memory, range 32, base rxfbf00000, size 131072, enabled bar [14] = type Memory, range 32, base rxfbf22000, size 4096, enabled bar [18] = type I/O Port, range 32, base rxf000, size 32, enabled cap 01[c8] = powerspec 2 supports D0 D3 current D0 cap 05[d0] = MSI supports 1 message, 64 bit enabled with 1 message cap 13[e0] = PCI Advanced Features: FLR TP
Steve: Was this on FreeBSD Head? Or a stable release?
(In reply to Sean Bruno from comment #1) It was HEAD, but I'm unable to reproduce now, could have been fixed or been a local issue. Thanks for checking, I'll let you know if it occurs again.
