So MDS_DIRECT_BUF_MAXSIZE size is used to send for for both previous & current versions of Opensaf nodes which are using MDS TCP as transport.

The kernel doubles this value (to allow space for bookkeeping over-head) when it is set using setsockopt(),and this doubled value is returned by getsockopt(). The default value is set to DTM_SOCK_SND_RCV_BUF_SIZE=126976 Note :This path is on top of Hans Feldt published on 4-29-2014 10:58 AM. changeset 2be313c0ee8254d6452e24dcaa1af4548845ddf7 Author: A V Mahesh <[email protected]> Date: Mon, 19 May 2014 10:04:45 +0530 dtm: make TCP_NODELAY set socket option configurable [#654] Made TCP_NODELAY configurable to specifi whether MDS TCP transport should follow the Nagle algorithm for deciding when to send data.By default, TCP will follow the Nagle algorithm is disable this behavior , can be configured to TRUE(1) or FALSE(0) Note :This path is on top of Hans Feldt published on 4-29-2014 10:58 AM.

Demonstrate some level of runtime or other sanity testing. ___ You have ^M present in some of your files. These have to be removed. ___ You have needlessly changed whitespace or added whitespace crimes like trailing spaces, or spaces before tabs. ___ You have mixed real technical changes with whitespace and other cosmetic code cleanup changes. These have to be separate commits. ___ You need to refactor your submission into logical chunks; there is too much content into a single commit. ___ You have extraneous garbage in your review (merge commits etc) ___ You have giant attachments which should never have been sent; Instead you should place your content in a public tree to be pulled. ___ You have too many commits attached to an e-mail; resend as threaded commits, or place in a public tree for a pull. ___ You have resent this content multiple times without a clear indication of what has changed between each re-send. ___ You have failed to adequately and individually address all of the comments and change requests that were proposed in the initial review. ___ You have a misconfigured ~/.hgrc file (i.e. username, email etc) ___ Your computer have a badly configured date and time; confusing the the threaded patch review. ___ Your changes affect IPC mechanism, and you don't present any results for in-service upgradability test. ___ Your changes affect user manual and documentation, your patch series do not contain the patch that updates the Doxygen manual. ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
