2009-07-20tty: fix chars_in_buffersAlan Cox
This function does not have an error return and returning an error is instead interpreted as having a lot of pending bytes. Reported by Jeff Harris who provided a list of some of the remaining offenders. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-10-13tty: ipw need reworkingAlan Cox
This came in via another tree and unfortunately is rather broken on the tty side. Comment the apparent locking problems for someone who knows the driver to look at. Fix the termios and other ioctl handling. The driver was calling the wrong methods for what it wanted to do but the right ones existed so its a simple fix up.

2008-08-31pcmcia: remove unused argument to pcmcia_parse_tuple()Dominik Brodowski
Since we're just parsing the tuple being passed to this function, we don't need any device-specific information. Also, remove the call to pcmcia_validate_cis() from pcmciamtd.c, since it is already called by the PCMCIA core. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2008-08-23pcmcia: deprecate CS_SUCCESSDominik Brodowski
Instead of using own error or success codes, the PCMCIA code should rely on the generic return values. Therefore, replace all occurrences of CS_SUCCESS with 0. CC: netdev@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

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.

2008-06-06ipwireless: Fix blocked sendingDavid Sterba
Packet sending is driven by two flags, tx_ready and tx_queued. It was possible, that there were queued data for sending and hardware was flagged as blocked but in fact it was not. The tx_queued was indicator but should be really a counter else first fragmented packet resets tx_queued flag, but there may be pending packets which do not get sent. New semantics: tx_ready - set, if hw is ready to send packet, no packet is being transferred right now set the flag right at the place where data are copied into hw memory and not earlier without checking if it was succesful tx_queued - count of enqueued packets, including fragments Tested-by: Michal Rokos <michal.rokos@gmail.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

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).
