Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
igc: Reduce TSN TX packet buffer from 7KB to 5KB per queue<br />
<br />
The previous 7 KB per queue caused TX unit hangs under heavy<br />
timestamping load. Reducing to 5 KB avoids these hangs and matches<br />
the TSN recommendation in I225/I226 SW User Manual Section 7.5.4.<br />
<br />
The 8 KB "freed" by this change is currently unused. This reduction<br />
is not expected to impact throughput, as the i226 is PCIe-limited<br />
for small TSN packets rather than TX-buffer-limited.
