From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alessandro Rubini Date: Fri, 7 Aug 2009 13:58:45 +0200 Subject: [U-Boot] [PATCH 0/4] Network defrag Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de I finally fixed the defrag code, testing with NFS as well. Didn't take performance figures, tough, for lack of time. I wanted to do "config + environment" for the NFS case, like tftp, but didnt' do the second step out of laziness (also, the source file has long lines while I have 80 columns). For the record, I added the check on ip_src and ip_dst, but everything stopped working. So I reverted that instead of entering a long debugging session. The CONFIG_NET_MAXDEFRAG argument is the actual payload, so I add NFS overhead to that figure, which is expected to a beautiful 4096 or 8192. I feel this is better than other options, as the person writing the config is not expected to know how much protocol overhead is there.
