linux-stable.git/drivers/staging, branch linux-2.6.38.y Linux kernel stable tree staging: r8712u: Fix driver to support ad-hoc mode 2011-06-03T01:34:13+00:00 Jeff Chua jeff.chua.linux@gmail.com 2011-04-27T16:25:14+00:00 ea1e05a4044e3ef488ee43098f89b4a34c034837 commit 62819fd9481021db7f87d5f61f2e2fd2be1dfcfa upstream. Driver r8712u is unable to handle ad-hoc mode. The issue is that when the driver first starts, there will not be an SSID for association. The fix is to always call the "select and join from scan" routine when in ad-hoc mode. Note: Ad-hoc mode worked intermittently before. If the driver had previously been associated, then things were OK.

USB: fix regression in usbip by setting has_tt flag 2011-05-09T22:06:41+00:00 Alan Stern stern@rowland.harvard.edu 2011-05-02T18:21:44+00:00 a41ee1d9242adc1cd4eaad4fcae727f778c394a9 commit cee6a262550f53a13acfefbc1e3e5ff35c96182c upstream. This patch (as1460) fixes a regression in the usbip driver caused by the new check for Transaction Translators in USB-2 hubs. The root hub registered by vhci_hcd needs to have the has_tt flag set, because it can connect to low- and full-speed devices as well as high-speed devices.

After Quick Migration, the network is not immediately operational in the current context when receiving RNDIS_STATUS_MEDIA_CONNECT event. So, I added another netif_notify_peers() into a scheduled work, otherwise GARP packet will not be sent after quick migration, and cause network disconnection.

For isochronous packets the actual_length is the sum of the actual length of each of the packets, however between the packets might be padding, so it is not sufficient to just send the first actual_length bytes of the buffer. To fix this and simultanesouly optimize the bandwidth the content of the isochronous packets are send without the padding, the padding is restored on the receiving end.
