    sfc: Allow resets to be upgraded; use atomic ops for safety · a7d529ae
    Ben Hutchings authored
    Currently an attempt to schedule any reset is ignored if a reset
    is already pending.  This ignores the relative scopes - if the
    requested reset is greater in scope then the scheduled reset should
    be upgraded accordingly.
    
    There are also some race conditions which could lead to a reset
    request being lost.  Deal with them by using atomic operations on a
    bitmask.  This also makes tests on reset_pending easier to get right.
