[CP]
This function - from what I understand after review, is looping through all
algorithms in DPDK crypto, and then checking if each is supported by each
device?
Could we instead just take the capabilities list from one device as the
starting point - That will be the max list of capabilities, they will only get
knocked out if not supported on the 2nd/3rd device etc.

Some trials I did with this patch showed some issues.
1. For QAT + AESNI_MB I get all skipped tests. I would have expected some
common algs here.

2. For 2 openssl devices I get 3 failures, which is curious as they are the
same. Seems to be a space issue:
USER1: Operation status 2
USER1: No space for aad in single mbuf
EAL: Test assert crosscheck_all_devices line 776 failed: Error occurred during
processing
EAL: Test assert crosscheck_with_profile_run line 841 failed: Error occurred
during encryption
Thanks,
Ciara
