CONFIG_ISOTP_RX_SF_FF_BUF_COUNT

Number of SF and FF data buffers for receiving data

Type: int

Help

This buffer is used for first and single frames. It is extra because the
buffer has to be ready for the first reception in isr context and therefor
is allocated when binding.
Each buffer will occupy CAN_DL - 1 byte + header (sizeof(struct net_buf))
amount of data.
