For the benefit of others that might be interested in this topic:
Turns out the issue was rooted in use of a LINK instead of an INTERFACE
statement when defining the OSA in z/OS. Once converted to INTERFACE, things
worked as expected.
Otherwise, in case of any issues:
You can find materials at

check the FAQ at https://linux-on-z.blogspot.com/p/smc-faq.html, and the
troubleshooting section at

Here's an outline of what has to be done to get SMC-D up and running on Linux:
# Hotplug ISM device if not yet visible via lspci command (see next step)
# Alternative: Use echo 1 > /sys/bus/pci/slots/00000080/power if smc_rnics is
# not available
$ smc_rnics -e 80
# Verify presence of ISM device
# NOTE: No extra setup for VLAN usage required
$ lspci
0001:00:00.0 Non-VGA unclassified device: IBM Internal Shared Memory (ISM)
virtual PCI device
# Run application using smc_run
$ smc_run foo_socks
# Verify that SMC is really used (see 'SMCD' in final column)
$ smcss -a
