I am writing a program that collects and displays network interface metrics located in the /sys/class/net/ folder.
When I was reading about the meaning of rx_dropped value, I came to the conclusion that this value as many possible causes, such as the ones specified in the first answer of this post:
ifconfig eth0 RX dropped packets
However, I cannot find any information on the tx_dropped value. I first though it would be related to TCP segments sent that did not get an Aknowledge and would therefore be dropped from the queue.
However, I was running curl 8.8.7.5, which would obviously result in retransmissions that I could watch in Wireshark, but the tx_dropped value remained 0.
Actually, in all the times I've run my program, I've never seen tx_dropped with a value other than 0.
What situation would make tx_dropped increase?
