Maximum number of tx retries

└─>Maximum number of tx retries
In linux kernel since version 2.6.12  
Specifies the number of times the driver attempts to transmit
a message before giving up, if the transmit queue of the ATM card
is transiently saturated.

Saturation of the transmit queue may occur only under extreme
conditions, e.g. when a fast host continuously submits very small
frames (<64 bytes) or raw AAL0 cells (48 bytes) to the ATM adapter.

Note that under common conditions, it is unlikely that you encounter
a saturation of the transmit queue, so the retry mechanism never
comes into play.
