Question on Partial Checksum in TCP/IP

2001-06-04 Thread Bharath Madhavan
Hello all, I am trying to understand a little bit about the TCP path in the Linux kernel. I saw that while we were even copying the user data into kernel space, we were doing the partial checksum of the data portion alone (as the TCP header is not yet filled up) and storing it in

ferent set of drivers at the socket level, that will do the trick I think. Is this easy? Thanks a lot Bharath -Original Message- From: David S. Miller [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 24, 2001 7:08 PM To: Bharath Madhavan Cc: '[EMAIL PROTECTED]' Subject: RE: Accelerated TCP/

Accelerated TCP/IP support from kernel

2001-05-24 Thread Bharath Madhavan
Hello all, I am looking into a scenario where we have a NIC which performs all the TCP/IP processing and basically the core CPU offloads all data from the socket level interface onwards to this NIC. Can Linux do this as of now. I saw some limited support like TCP/IP checksumming being

Speeding up VFS using HW assist

Hello All, I will be using Linux as the OS for an embedded system. I was looking into 2.4.4 kernel code and saw the dcache implementation in VFS which is pretty neat and fast by itself. My question is, will I gain any considerable efficiency in file system access if I can move this
