net: qmi_wwan: add Olivetti Olicard modems

2014-06-26T19:17:33+00:00

[ Upstream commit ba6de0f5304ccdc45ae260e7e0feb6e0ef2dd558 ] Lars writes: "I'm only 99% sure that the net interfaces are qmi interfaces, nothing to lose by adding them in my opinion." And I tend to agree based on the similarity with the two Olicard modems we already have here. Reported-by: Lars Melin Signed-off-by: Bjørn Mork Signed-off-by: David S.

ipheth: Add support for iPad 2 and iPad 3

2014-06-02T23:11:55+00:00

Each iPad model has a different product id, this patch adds support for iPad 2 (pid 0x12a2) and iPad 3 (pid 0x12a6). Note that iPad 2 must be jailbroken and a third-party app must be used for tethering to work. On iPad 3, tethering works out of the box (assuming your ISP is nice).

net: qmi_wwan: interface #11 in Sierra Wireless MC73xx is not QMI

2014-06-02T21:00:28+00:00

This interface is unusable, as the cdc-wdm character device doesn't reply to any QMI command. Also, the out-of-tree Sierra Wireless GobiNet driver fully skips it. Signed-off-by: Aleksander Morgado Acked-by: Bjørn Mork Signed-off-by: David S. Miller

net: cdc_mbim: handle unaccelerated VLAN tagged frames

2014-05-09T17:29:53+00:00

This driver maps 802.1q VLANs to MBIM sessions. The mapping is based on a bogus assumption that all tagged frames will use the acceleration API because we enable NETIF_F_HW_VLAN_CTAG_TX. This fails for e.g. frames tagged in userspace using packet sockets. Such frames will erroneously be considered as untagged and silently dropped based on not being IP. Fix by falling back to looking into the ethernet header for a tag if no accelerated tag was found.

net: cdc_ncm: fix buffer overflow

2014-05-05T19:19:31+00:00

Commit 4d619f625a60 ("net: cdc_ncm: no point in filling up the NTBs if we send ZLPs") changed the padding logic for devices with the ZLP flag set. This meant that frames of any size will be sent without additional padding, except for the single byte added if the size is a multiple of the USB packet size. But if the unpadded size is identical to the maximum frame size, and the maximum size is a multiplum of the USB packet size, then this one-byte padding will overflow the buffer. Prevent padding if already at maximum frame size, letting usbnet transmit a ZLP instead in this case.
