drivers/net: using spin_lock_irqsave() in net_send_packet()
spin_unlock_irq() will enable interrupt in net_send_packet(),
this patch changes it to spin_lock_irqsave/spin_lock_irqrestore,
so that it doesn't enable interrupts when already disabled,
and netconsole would work properly over cs89x0/isa-skeleton.
Call trace:
netconsole write_msg()
{
...
-> spin_lock_irqsave();
-> netpoll_send_udp()
-> netpoll_send_skb()
-> net_send_packet()
->...
-> spin_unlock_irqrestore();
...
}
