    NFC: nfcsim: Simulate lost frames through debugfs entry · 2a0fe4fe
    Thierry Escande authored
    This patch allows to simulate the lost of frames exchanged between the 2
    nfcsim devices through a control entry in the debugfs and is used as
    follow:
    
     echo n > /sys/kernel/debug/nfcsim/nfcX/dropframe
    
    Where n specifies the number of frames to be dropped between 0 and 255
    and nfcX is either nfc0 or nfc1, one of the two nfcsim devices.
    
    In the following example, the next frame that should be sent by the nfc0
    device will be dropped and thus not received by the nfc1 device:
    
     echo 1 > /sys/kernel/debug/nfcsim/nfc0/dropframe
    
    The value of 0 can be used to reset the dropframe counter.
