2008-07-28ipwireless: Preallocate received packet buffers with MRU sizeDavid Sterba
ipwireless: Preallocate received packet buffers with MRU size Packets are assembled from link size (~300 bytes) up to PPP MRU (1500 by default). Try to preallocate full size rather than repeatedly advance buffer size by 256 bytes.

2008-07-28ipwireless: Increase PPP outgoing queue sizeDavid Sterba
ipwireless: Increase PPP outgoing queue size Increase default size of PPP outgoing queue. Currently set to 1, which means that a packet quickly following another pushed by PPP must wait until hardware actually sends the previous and PPP has to be waken up by ppp_wakeup(). This slows down upstream. Now PPP can push more packets at once which get buffered inside driver and pushed immediatelly to hardware when previous packet is out. Experiments show that size = 10 is quite good for all connection types (GPRS/EDGE/UMTS) and gains 4 KB/sec of upload for UMTS for batch uploads. Need for higher queue size than 10 occures in only < 0.1 % of cases.

2008-02-07ipwireless: driver for PC Card 3G/UMTS modemDavid Sterba
The device is manufactured by IPWireless. In some countries (for example Czech Republic, T-Mobile ISP) this card is shipped for service called UMTS 4G. It's a piece of PCMCIA "4G" UMTS PPP networking hardware that presents itself as a serial character device (i.e. looks like usual modem to userspace, accepts AT commands, etc).
