Cumulonimbusdo you see anything in the arp table on the f5 (in tmsh 'show net arp', from bash 'arp -n') or your laptop? are any AFM or packet filter rules defined on the f5 that could prevent ICMP to/from the self-IP? have you tried running tcpdump on the f5?
f5 config should be vlan with necessary interface as untagged. unique self-ip should be assigned to that vlan as traffic-group-local-only.
you could try another interface

Cumulonimbusdoubtful as you do not know what the problem is. if you see arp requests on the f5 when you ping, physical is fine. if you see arp requests but no arp response, then it's probably IP-related. possibly the F5 doesn't have the address in the arp request, or the self-IP's mask is incorrect. can you share your self-IP config (tmsh list net self)?
