Sjors Hettinga 3bcd8d1ee1 net: socket: Use exponential backoff in case of polling errors
Some errors can occur in the sending process that have to be handled
in a polling fasion instead of blocking using semaphores. In this case
apply an exponentially growing backoff time. This will allow for fast
reactions in most situations and prevents high system loads in case
resolving the situation takes a little longer.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
