Subject: [PATCH] sftp: fix uploads being 65% slower than they should be with
 crypt

The block size for crypt is 64k + a few bytes. The default block size
for sftp is 32k. This means that the blocks for crypt get split over 3
sftp packets two of 32k and one of a few bytes.

However due to a bug in pkg/sftp it was sending 32k instead of just a
few bytes, leading to the 65% slowdown.

This was fixed in the upstream library.

This bug probably affected transfers from over the network sources
also.

Fixes #6763
