commit d84cc9c9524e ("crypto: talitos - fix ECB algs ivsize")
wrongly modified CBC algs ivsize instead of ECB aggs ivsize.

This restore the CBC algs original ivsize of removes ECB's ones.

and similar for ecb(des), ecb(des3_ede).

Current patch is incorrect: it adds ivsize for ecb and removes it from cbc.

Very strange. Looks like there has been some rebase weirdness which have applied the patch on the wrong block at some point on my side, probably due to the fact that both blocks have the two previous and following lines identical.

I've now rebased my serie on cryptodev/master and have the same behaviour as you. I'll resend the series without this patch.
