Theory of Operation:
The Silicom Bypass Network Interface Cards (NICs) are network cards with paired ports (2 or 4).
The pairs either act as a "wire" allowing the network packets to pass or insert the device in
between the two ports. When paired with the on-board hardware watchdog or other failsafe,
they provide high availability for the network in the face of software outages or maintenance.
The software requirements are for a kernel level driver that interfaces with the bypass and watchdog,
as well as for control software. User control can be either the provided standalone executable
(/bin/bpctl) or the API exposed by the Silicom library.
