From 4133da73067af0417c623eb4ad5e85081ccbf4b4 Mon Sep 17 00:00:00 2001 From: Xiang Gao Date: Tue, 10 Oct 2017 22:31:49 -0400 Subject: mac80211: aead api to reduce redundancy Currently, the aes_ccm.c and aes_gcm.c are almost line by line copy of each other. This patch reduce code redundancy by moving the code in these two files to crypto/aead_api.c to make it a higher level aead api. The file aes_ccm.c and aes_gcm.c are removed and all the functions there are now implemented in their headers using the newly added aead api.
