Hi,

Lets say an application sends 100 packets to IP-address X. The Linux
ARP-table does not have the corresponding MAC-address and hence have
to find the MAC-address and sends out an ARP-request. During the MAC-
address resolution the Linux IP-stack drops packets towards IP-address
X.

The question is which packets are dropped and which are kept?

Lets say the application has sent 50 packets while the MAC-address is
unknown, and when it's time for the Linux kernel/IP-stack to send
packet number 51 the MAC-address is known.

What packets are dropped and what are sent? Are all 50 packets
dropped, and the first packet being sent is packet 51?

Or, is the first packet stored/saved by the Linux kernel, and sent
out, and then packet number 51 is sent (this is the behavior I would
like to have for my specific application).

Or is this configurable in the Linux kernel/IP-stack somehow?

why would it do that?
