"Shim" driver for backward compatibility with io-net
io-pkt-variant -d shim "io-net_drvr [drvr_opt,...]"
where variant is one of v4, v4-hc, or v6-hc.
The devnp-shim.so shared object is a "shim" driver that lets io-pkt support devn-* drivers that were written for io-net.
Explicitly loading the shim driver is usually unnecessary; io-pkt loads the shim automatically. For example, if you type:
io-pkt -d some_driver
then io-pkt searches for devnp-some_driver.so and loads it as a native driver if found. If not found, io-pkt tries to load devn-some_driver.so via the shim.
If you type:
io-pkt -d /lib/dll/devn-some_driver.so
then io-pkt notices that the driver is an io-net one and loads it via the shim.
io-pkt -d shim devn-speedo.so io-pkt -d shim "/lib/dll/devn-speedo.so transmit=1024,receive=1024"
