whitequark 89b7c9e091 Update smoltcp. 
Fixes #840.

whitequark 20f43d5792 firmware: fix ethmac MTU value. 
1500 is the maximum payload size, not maximum frame size.

whitequark f26e698f31 Revert "firmware: reduce ethmac maximum burst size by one." 
This reverts commit 2231b16e0a.

Only made a difference with TRACE log level to UART, i.e. only
because UART was the bottleneck.

whitequark 2231b16e0a firmware: reduce ethmac maximum burst size by one. 
Empirically, this much reduces packet loss. I'm not really sure why,
but it seems safe to do the change.

whitequark f5e1d9568d firmware: update smoltcp. 2017-08-24 05:50:59 +00:00
whitequark 5bbb05362b runtime: update smoltcp. 2017-03-07 11:36:28 +00:00
whitequark b95db4fa4e Use four ethmac buffers instead of two. 
This should address an issue where the host sends a packet burst,
the second packet in a burst gets dropped, the rest also gets
dropped since smoltcp doesn't do reassembly, and the entire dance
is repeated on every retransmit.

whitequark 527b1e986c firmware: integrate smoltcp instead of lwip. 2017-01-23 13:59:34 +00:00
