Up until now, when configuring the HT possible set of Tx MCS only Rx MCS were considered, assuming they are the same as the Tx MCS.

Here's an example with KMail: That is true. OTOH, sending them as individual messages (or as replies to a single "0/N" message) can cause them to arrive out of order. In most cases patches sent as a group need to be applied in a certain order. In many cases they will fail to apply, and in others they might apply out of order but not be "bisectable" out of order. IMHO it is a lot easier to deal with the "funny looking" mailbox window than to deal with the issues caused by misordered patches. John -- John W.
