Hello. My system FreeBSD 12.2 . I have an igb network card. Found out that the igb driver has merged with em. Where are the system parameters? hw.em.rxd="4096" hw.em.txd="4096" # sysctl hw.em.rxd sysctl: unknown oid 'hw.em.rxd' https://www.freebsd.org/cgi/man.cgi?query=em&apropos=0&sektion=4&manpath=FreeBSD+12.2-RELEASE&arch=default&format=html *LOADER TUNABLES* <https://www.freebsd.org/cgi/man.cgi?query=em&apropos=0&sektion=4&manpath=FreeBSD+12.2-RELEASE&arch=default&format=html#end>; Tunables can be set at the loader(8) <https://www.freebsd.org/cgi/man.cgi?query=loader&sektion=8&apropos=0&manpath=FreeBSD+12.2-RELEASE>; prompt before booting the kernel or stored in loader.conf(5) <https://www.freebsd.org/cgi/man.cgi?query=loader.conf&sektion=5&apropos=0&manpath=FreeBSD+12.2-RELEASE>. *hw.em.rxd* Number of receive descriptors allocated by the driver. The de- fault value is 1024 for adapters newer than 82547, and 256 for older ones. The 82542 and 82543-based adapters can handle up to 256 descriptors, while others can have up to 4096. *hw.em.txd* Number of transmit descriptors allocated by the driver.
