net_pkt_alloc_buffer() deducts the free space from the requested number of bytes. As ppp_save_byte() calls net_pkt_alloc_buffer() when the packet has one byte available still, this causes all but the first net_buf in the packet to be of size CONFIG_NET_BUF_DATA_SIZE - 1. Consequences: - With CONFIG_NET_BUF_FIXED_DATA_SIZE enabled, one byte per net_buf gets wasted. - CONFIG_NET_BUF_DATA_SIZE has typically an even, likely even a power of two value. Using exactly one byte less per buffer causes operations that require aligned memory (e.g. DMA) to become inefficient or to not work at all.
