Subject: | [lwip-users] low level output question |
Date: | Fri, 8 May 2009 10:19:07 -0600 |
In the Xilinx lwip 1.3.0 port the low_level_output function
basically copies the entire pbuf to the Ethernetlite MAC using the pbuf len (or
total length if the pbuf is chained). This seems inefficient, since the
actual packet length could be much smaller than the pbuf length. It seems
like it would be more efficient to just to copy the actual packet to the MAC
rather than the entire pbuf. How should this be done?
