I have completed but not yet sent some updates for rtl8192ee. Using them and 
kernel 5.3-rc6, I am getting the following:

--- 192.168.1.1 ping statistics ---
100 packets transmitted, 100 received, 0% packet loss, time 99134ms
rtt min/avg/max/mdev = 0.881/1.487/8.198/0.844 ms

This is using the "old" firmware with the following md5sum:

c8d25646cbc9efdcb818fc95ad5836a9  /lib/firmware/rtlwifi/rtl8192eefw.bin

The new driver patches convert a set of macros to read and write the descriptors 
into inline routines. The calling sequences are also converted from u8 * to 
__le32 *, but I would not expect much improvement with the latter changes.

Using a local speed test web site, I am getting 100 Mbps download and 80 Mbps 
upload rates.
