/* CLM file is cut into pieces of MAX_CHUNK_LEN.
* It is relatively small because dongles (FW) have a small maximum size
* input payload restriction for ioctl's ... something like 1900'ish bytes.
* So chunk len should not exceed 1400 bytes
*
* NOTE: CONFIG_NET_ETH_PKTSIZE is the MTU plus the size of the Ethernet
* header (14 bytes).
