Chris's patches were taken as base. There were efforts to launch it on

Functions that were exposed in "net: ipv6: Add IPv6 basic primitives"

functions are: net_ip6_handler() - IPv6 packet handler for incoming

csum_ipv6_magic() - compute checksum of IPv6 "psuedo-header" per RFC2460

This functions is used as a converter from IPv6 address string notation
to struct ip6_addr that is used everywhere in IPv6 implementation. For
example it is used to parse and convert IPv6 address from tftpboot
command. Conversion algorithm uses two passes, first to verify syntax and
locate colons and second pass to read the address. In case of valid IPv6
address it returns 0.

The rx descriptor list is in cached memory, and there may be multiple
descriptors per cache-line. After reclaim_rx_buffers marks a descriptor
as unused it does a cache flush, which causes the entire cache-line to
be written to memory, which may override other descriptors in the same
cache-line that the controller may have written to.
The fix skips freeing descriptors that are not the last in a cache-line,
and if the freed descriptor is the last one in a cache-line, it marks
all the descriptors in the cache-line as unused.
This is similarly to what is done in drivers/net/fec_mxc.c
In my case this bug caused tftpboot to fail some times when other
packets are sent to u-boot in addition to the ongoing tftp (e.g. ping).
The driver would stop receiving new packets because it is waiting
on a descriptor that is marked unused, when in reality the descriptor
contains a new unprocessed packet but while freeing the previous buffer
descriptor & flushing the cache, the driver accidentally marked the
descriptor as unused.
