[U-Boot] [PATCH v3 7/8] net: remove CONFIG_MCAST_TFTP
Simon Goldschmidt
simon.k.r.goldschmidt at gmail.com
Sat Nov 17 12:25:03 UTC 2018
This option seems unused as no mainline board enables it and it does
not compile since some years.
Additionally, it has a potential buffer underrun issue (reported as
a side node in CVE-2018-18439).
Instead of trying to fix a thing noone seems to use, let's rather
drop dead code.
