Hi,
I am trying to implement an extension to the FreeBSD TCP stack. In order to
do that, I have a question regarding the calculation of the pipe
variable, the amount of data that the sender calculates as being inflight.
I am puzzled for the case when no
Hey Everyone,
Has anyone seen IGMP traffic hit there pflog interface even if there are no
rules matching that tell it to log ?
Anyone that has a pointer to eliminate the logging of the IGMP traffic would be
extremely helpful. This has been fairly frustrating up to this point trying to

Hi folks,
I understand better why I am seeing EINVAL intermittently when sending
data from Samba via SMB2.
The ixgbe driver, for TSO reasons, limits the amount of data that can
be DMA'd to 65535 bytes. It returns EINVAL for any mbuf chain larger
than that.
The SO_SNDBUF for that socket is set
.. and please file a PR. I'm sure Jack will love this kind of feedback. :)
Thanks for doing this debugging! I'm glad to see others getting dirty
in the network stack.

If you don't use TSO you will hurt your TX performance significantly from
the tests that I've run. What exactly is the device you are using, I don't
have the source in front of me now, but I'm almost sure that the limit is
not 64K but 256K, or are you using some ancient version of the driver?
Yes, I checked: #define IXGBE_TSO_SIZE 262140
So, the driver is not limiting you to 64K assuming you are using a
version of recent vintage.

The stack won't generate TCP and IP packets larger than 64K. However
the ethernet header gets prepended to it
Hmmm, so its the stack, can that be easily increased Andre?

Ahh, Twinville, new hardware :) The version at the tip is 2.5.8 and I am
working on version 2.5.12 internally that I hope to commit next week...
so your version is a bit old :) I would do some testing on newer code.
