[meta-intel] [warrior][PATCH 2/4] linux-intel/4.19: update to v4.19.73

[Vincent Prince]

There are 3 options for those using CAN bus:

1- set sysctl net.core.default_qdisc back to pfifo_fast
2- remove CONFIG_NET_SCH_FQ_CODEL kernel option
3- apply kernel patch from
https://lore.kernel.org/netdev/20190327165632.10711-1-mkl@pengutronix.de/t/#m5f86a2d284d8c8cf11d2f1786575b10fe4be5eb6

Third option is what I prefer, but it depends on kernel patching policy ;)
