Re: Linux kernel updates and ip_crossover patch

[Mehulkumar J Patel <mehul.patel@xxxxxxxxxx>]

Hi,

We at IBM need IP CROSSOVER module as part of kernel source.

I sent the request to SuSe for the same and they got back to me and their response is in this mail thread below.

Can you please let me know what do you think about IP CROSSOVER feature ?

best regards,
Mehul.

Good morning,

did you sent the patch to netdev@xxxxxxxxxxx?
What opinion have the network and iptables maintainers about this feature?
