Analyze and fix the following issue in the Linux kernel code: iwl3945: iwl3945_mac_get_tsf() should not return zero
Problem Details: The problem fixed here is that iwl3945_mac_get_tsf() returns 0, as the function is not implemented, and this is considered as a valid value by the mac layer in mlme.c:1605. The consequence is that the STA in ad-hoc mode is inserted/removed quite frequently due to IBSS merging. This patch fixes : http:...
