umb: aggregate packets on tx

2016-12-12 Thread Gerhard Roth
The current umb(4) implementation needs one USB transfer for every packet that is sent. With the following patch, we can now aggregate several packets from the ifq into one single USB transfer. This may speed up the tx path. And even if it doesn't, at least it reduces the number of transfers
