open source still includes binary blobs

[Nieuwejaar]

There are at least two binary blobs buried in the source:

pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.a
pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.so

It looks like this is mostly code for accessing registers in the tofino and serdes:

nils:~/dev/tofino-sde$ nm ./pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.a | grep pkgsrc
[...]
./pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.a[bf_ll_eth100g_reg_rspec_if.c.o]:
./pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.a[bf_ll_eth400g_mac_rspec_if.c.o]:
./pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.a[bf_ll_eth400g_pcs_rspec_if.c.o]:
./pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.a[port_mgr_tof2_umac.c.o]:
./pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.a[port_mgr_tof2_umac3.c.o]:
./pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.a[port_mgr_tof2_umac4.c.o]:
./pkgsrc/bf-drivers/src/port_mgr/port_mgr_lib/libport_mgr_hw.a[credo_sd_access.c.o]:

I can imagine that the credo file contains source that Intel can't distribute, but I don't know why the intel/barefoot code isn't available.

This is a standard ELF library, but seems to be mostly self-contained:

Hopefully I can fashion a compatibility wrapper to get this Linux library to work on illumos. I'm almost certain I could build an illumos-native version of the library from the old closed-source SDE, but I suspect that would be frowned upon.
