Much of the scanning work was supported by Atheros. The 11n work was supported by Marvell. 2007-04-19T13:09:57Z Sepherosa Ziehau sephe@FreeBSD.org 2007-04-19T13:09:57Z urn:sha1:b03cfe239638b8b94b3e652a9184ffbf372ed25d - For ural(4): o Fix node leakage in ural_start(), if ural_tx_mgt() fails. o Fix mbuf leakage in ural_tx_{mgt,data}(), if usbd_transfer() fails. o In ural_tx_{mgt,data}(), set ural_tx_data.{m,ni} to NULL, if usbd_transfer() fails, so they will not be freed again in ural_stop().
