This patch moves re-works the implementation of event subscription via debugfs. For this: * it tells cmd.c and cmdresp.c about CMD_802_11_SUBSCRIBE_EVENT * removes lots of low-level cmd stuff from debugfs.c * create unified functions to read/write snr, rssi, bcnmiss and failcount * introduces #define's for subscription event bitmask values * add a function to search for a specific element in an IE (a.k.a. TLV) * add a function to find out the size of the TLV. This is needed because lbs_prepare_and_send_command() has an argument for a data buffer, but not for it's lengths and TLVs can be, by definition, vary in size. * fix a bug where it was not possible to disable an event Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.
