From 16cdc2daa07986243751a9f545aa287c60e04ced Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Sat, 23 Nov 2019 17:58:59 +0000 Subject: [PATCH] net: tftp: Fix too small block size Commit b618b3707633 ("net: Convert CONFIG_TFTP_BLOCKSIZE to Kconfig") accidentally set the default *option* TFTP block size to 512 bytes, even though the comment in the code says that this is a terrible choice. Most boards didn't define the symbol before, so they got the default block size of 1468 bytes before, but now use 512 bytes, which is also the fallback. This leads to both abysmal performance and a lot of hashes printed on the screen (one character for every 5K), which is both annoying and slow over serial links. Set the default block size in Kconfig back to the value it had before. This improves TFTP performance from 2.8 MB/s to 6.9 MB/s on a Pine64.
