no, but b in bpf stands for Berkeley, so the interface originated from bsd.

bpf is a virtual machine to process network packets in kernel space. So it is sort of like the low level assembly language of network processing. It is entirely possible to build a high-level packet filtering language that compiles down to bpf, But I don't think PF does this. PF appears to use it's own specific network processing interface.

Note the pf specific ioctls used to inject rules into the kernel.

PF stands for packet filter in both cases
