+Subject: [PATCH 14/25] crypto: crypto4xx - fix off-by-one AES-OFB
+
+I used aes-cbc as a template for ofb. But sadly I forgot
+to update set_key method to crypto4xx_setkey_aes_ofb().
+
+this was caught by the testmgr:
+alg: skcipher: Test 1 failed (invalid result) on encr. for ofb-aes-ppc4xx
+00000000: 76 49 ab ac 81 19 b2 46 ce e9 8e 9b 12 e9 19 7d
+00000010: 50 86 cb 9b 50 72 19 ee 95 db 11 3a 91 76 78 b2
+00000020: 73 be d6 b8 e3 c1 74 3b 71 16 e6 9e 22 22 95 16
+00000030: 3f f1 ca a1 68 1f ac 09 12 0e ca 30 75 86 e1 a7
+
+With the correct set_key method, the aes-ofb cipher passes the test.
