Status: Open
Priority: Low
Title: READ-AHEAD THROTTLING
Description: Read-ahead buffers capture incoming TCP data when no user
thread is recv-ing the data. Should add some driver call to
support throttling; when there is no listener for new data, the
driver should be throttled. Perhaps the driver should disable
RX interrupts when throttled and re-anable on each poll time.
recvfrom would, of course, have to un-throttle.
Status: Open. This is just a thought experiment. No changes are planned.
Priority: Low. This is not a bug but an enhancement idea.
Title: COMMON TCP BUFFERING
Description: TCP read-ahead logic and TCP write buffering logic use a
separate set of packet buffers. It seems like more efficient
use of the buffering would be had if a common pool of packet
buffers were used for both read-ahead and write buffering.
This would probably depend on having READ-AHEAD THROTTLING to
prevent run-awary read-ahead logic from consuming all buffers.
Status: Open. This is just a thought experiment. No changes are planned.
Priority: Low. This is not a bug but an enhancement idea.
Title: STANDARDIZE ETHERNET DRIVER STATISTICS
Description: Need to standardize collection of statistics from network
drivers. apps/nshlib ifconfig command should present

This setting specifies the size of one TCP/IP read-ahead buffer.

Optimally, the size of the read-ahead buffer will should the maximum
size of an incoming TCP packet payload (MSS). This MSS value is
determined by NET_BUFSIZE minus the size of TCP, IP, and Ethernet
