Description Nicolas Chautru 2024-03-20 20:07:50 CET 
The memory footprint has increased massively when the commit "97435d7906 net/bnxt: update Truflow core" was added.
The bss in my example going from 6M to 94M when building any dpdk-test applicationfor instance, when that commit is introduced. 
There are now notably huge memory reserved for cfa_tcam_mgr_* from the bnxt PMD visible from nm.

That issue is notably impacting v23.11 and still seen on main as of today. 

For now for application building with 23.11, we recommend to disable the net/bnxt through meson to avoid this issue.

I believe a proper fix is required from Broadcom bnxt: --cc Ajit Khaparde <ajit.khaparde@broadcom.com>, Somnath Kotur <somnath.kotur@broadcom.com>, Randy Schacher <stuart.schacher@broadcom.com>
