You mean the free buffer routine of [b]desballoc[/b] is always
called before gld_recv( ) or mac_rx( ) exit? If something goes
wrong, like the "Ping got stuck" issue that we discussed last week
happens and packets got buffered in system until name service
timeout, can the free buffer routine be called before gld_recv( )
or mac_rx( ) exit? If so, then I think we do not need a free rx
buffer list since the rx buffer is always freed after sending
packet upstream and we can re-use it.
But I see many network drivers still have free buffer list even if
their rx buffer were allocated using desballoc( ), why? I am very
confused.
One possibility is that drivers might be sending packets up with some
extra resources attached to them.
When the packet is consumed above, then it can be reused below along
with the associated resources (think dma).
