[Hemant] this is working fine for pmd_dpaa but not for pmd_dpaa2
I removed the filename_exp and introduced function based name=
Now the issue is the following warning
SONAME changed from 'librte_pmd_dpaa2.so.20.0' to 'librte_pmd_dpaa2.so.0.200.2'
The primary reason is that now pmd_dpaa2 has no symbol left for 20.0 section.
Following is not helping.
[suppress_file]
soname_regexp = ^librte_pmd_dpaa2
so, it seems for now, the filename_exp is the only option
