>Description:
I have a strange problem with sk(4) and dhcp:
dhcpcd -n sk0  results in 'time out', when I run it the second time, I get an 
IP address.
the first time runs at boot via /etc/rc.d/networks
Run dhcpcd manually after boot to get an IP address.
I can also reproduce the same problem when I do

 /etc/rc.d/network stop ; /etc/rc.d/network start ; dhcpcd -n sk0

when dhcp times out, the dhcp server actually see's no packets coming in.

dhcpcd -k sk0 ; dhcpcd -n sk0  works
dhcpcd -k sk0 ; ifconfig sk0 down ; dhcpcd -n sk0  results in time out
dhcpcd -k sk0 ; ifconfig sk0 down ; ifconfig sk0 up ; dhcpcd -n sk0 results in 
time out
dhcpcd -k sk0 ; ifconfig sk0 down ; ifconfig sk0 up ; sleep 3 ; dhcpcd -n  sk0  
works
sounds like the makphy(4) or sk(4) driver needs a delay for power on ?

Workaround: In /etc/ifconfig.sk0 put these lines:

up
!sleep 3
dhcp

this makes /etc/rc.d/network start working at boot.
