Further question on 'ifconfig' output

I asked a similar question earlier and got a very good answer but a new doubt came up. This is a few lines of a '/sbin/ifconfig' command on my PC:

RX packets:3781025 errors:0 dropped:0 overruns:0 frame:0
TX packets:1941909 errors:0 dropped:0 overruns:0 carrier:0

Does the RX and TX packets number shown here represent the number of correctly received packets or the total number of packets?
That is, to obtain the correct number of received packets, do we have to subtract the number of errors, dropped, and so forth?

Thanks.

inet_type(4)							   File Formats 						      inet_type(4)

NAME
inet_type - default Internet protocol type SYNOPSIS
/etc/default/inet_type DESCRIPTION
The inet_type file defines the default IP protocol to use. Currently this file is only used by the ifconfig(1M) and netstat(1M) commands. The inet_type file can contain a number of <variable>=<value> lines. Currently, the only variable defined is DEFAULT_IP, which can be assigned a value of IP_VERSION4, IP_VERSION6, or BOTH. The output displayed by the ifconfig and netstat commands can be controlled by the value of DEFAULT_IP set in inet_type file. By default, both commands display the IPv4 and IPv6 information available on the system. The user can choose to suppress display of IPv6 information by setting the value of DEFAULT_IP. The following shows the possible values for DEFAULT_IP and the resulting ifconfig and netstat output that will be displayed: IP_VERSION4 Displays only IPv4 related information. The output displayed is backward compatible with older versions of the ifconfig(1M) and netstat(1M) commands. IP_VERSION6 Displays both IPv4 and IPv6 related information for ifconfig and netstat. BOTH Displays both IPv4 and IPv6 related information for ifconfig and netstat. The command-line options to the ifconfig and netstat commands override the effect of DEFAULT_IP as set in the inet_type file. For example, even if the value of DEFAULT_IP is IP_VERSION4, the command example% ifconfig -a6 will display all IPv6 interfaces. EXAMPLES
Example 1: Suppressing IPv6 Related Output This is what the inet_type file must contain if you want to suppress IPv6 related output: DEFAULT_IP=IP_VERSION4 SEE ALSO
ifconfig(1M), netstat(1M) SunOS 5.10 16 Jun 1999 inet_type(4)
