Commit Message

Dr. David Alan Gilbert Sept. 18, 2024, 8:52 p.m. UTC 
From: "Dr. David Alan Gilbert" <dave@treblig.org>

net_hub_port_find is unused since 2018's commit
  af1a5c3eb4 ("net: Remove the deprecated "vlan" parameter")

qemu_receive_packet_iov is unused since commit
  ffbd2dbd8e ("e1000e: Perform software segmentation for loopback")

in turn it was the last user of qemu_net_queue_receive_iov.

Remove them.
