With earlier configured value sufficient number of CQEs are not being reserved for transmitted packets. Hence under heavy incoming traffic load, receive notifications will take away most of the CQ thus transmit notifications will be lost resulting in tx skbs not being freed. Finally SQ will be full and it will be stopped, watchdog timer will kick in. After this fix receive notifications will not take morethan half of CQ reserving the rest for transmit notifications. Also changed CQ & SQ sizes from 16k to 4k. This is also due to the receive notifications taking first half of CQ under heavy load and time taken by NAPI to clear transmit notifications will increase with higher queue sizes. Again results in SQ being stopped. Signed-off-by:
