Dear netdev,
I have one problem with my NIC driver: whenever I use
netif_receive_skb(skb) or netif_rx(skb) to indicate received packet,
iperf does work, but ftp does not work, because the kernel seemes not
kfree_skb(skb) when I use ftp. What??s wrong with my NIC driver? Any
suggestions will be appreciated. Thanks in advance.
When I use iperf to test my NIC driver, it seems okay. When I use ftp,
ftp client in kernel 2.6.22 and ftp server is ServUftp at windows2000,
it does work too. But, When I use windows2003 server and its contained
ftp server, my NIC driver can get file from that ftp server until the
memory is used out. When I get 3G file, then 3G memory will be used and
not freed.
The source code is at :

<http://sourceforge.krugle.com/kse/files?project=%22Attansic%20L1%20Gigabit%20Ethernet%20driver%22>
Please check the function at_clean_rx_irq() and at_alloc_rx_buffers() in
file at_main.c.
I dev_alloc_skb() and pci_map_single() skb in function
at_alloc_rx_buffers(), pci_unmap_page() and netif_rx() in function
at_clean_rx_irq(), CONFIG_AT_NAPI is not defined.
Thank csnook.

Okay, I didn't know you were talking about the atl1 driver. Are you
using the
in-tree driver in 2.6.22, or the pre-merge driver on sourceforge, or the
vendor
driver from Attansic/Atheros?
Also, can you test this again using the latest 2.6.23-rc7 kernel, with
the atl1 driver
included in that kernel?

I'm going to need way more information than that. I'm also not certain I'm the
best person to answer the question. I suggest asking the question again, with a
lot more info, to [EMAIL PROTECTED] You're welcome to CC me as well.
Please also post a link to the driver source so we can see what exactly you're
doing.
