Hello, it says nothing to be worry about

10 input errors, 6 CRC, 0 frame, 0 overrun, 4 ignored
0 watchdog, 64973071 multicast, 0 pause input
0 input packets with dribble condition detected
4 output errors, 0 collisions, 2 interface resets
0 babbles, 0 late collision, 0 deferred
4 lost carrier, 0 no carrier, 0 pause output
0 output buffer failures, 0 output buffers swapped out

I see same behaviour with bce input error on other servers running 
different FreeBSD amd64 versions (small bandwidth, small amount of 
errors) on the same switch, but I also see no input errors on other 
FreeBSD amd64 servers which are on the same switch(small bandwitdh, no 
errors). All servers don't hit any limits.

Only for information without providing any other details versions are as 
follows:

1.)8.2-STABLE FreeBSD 8.2-STABLE #0: Fri Sep 30 19:59:31 EEST 2011 - no 
input errors - very small bandwidth usage

2.)8.2-STABLE FreeBSD 8.2-STABLE #0: Tue Jul 19 15:38:26 EEST 2011 - 
6249 input errors since 40 days - small bandwidth usage

3.)8.2-STABLE FreeBSD 8.2-STABLE #0: Mon May 16 14:57:35 EEST 2011 - 2 
interfaces: 177 errors since boot, 331444 errors since boot - same 
bandwidth usage as server 2

4.)8.2-STABLE FreeBSD 8.2-STABLE #0: Mon May 16 17:16:30 EEST 2011 - no 
input errors - bandwidth usage as server 1

5.)8.1-STABLE FreeBSD 8.1-STABLE #0: Tue Oct 12 10:12:02 EEST 2010 - 
2711 ierrors in 6 months - ~50-60Mb/s bandwidth

6.)7.1-STABLE FreeBSD 7.1-STABLE #0: Thu Jan 29 10:21:42 EET 2009 - no 
errors - same bandwidth usage as server 1

7.)8.2-STABLE FreeBSD 8.2-STABLE #1: Wed Apr 20 10:43:34 EEST 2011 - 
3505 ierrors since boot - same bandwidth as server 5 (50-60Mb/s)

8.)8.0-STABLE FreeBSD 8.0-STABLE #0: Wed Dec 30 12:30:03 EET 2009 - 8015 
ierrors since boot - same bandwidth usage as server 2

9.)8.2-STABLE FreeBSD 8.2-STABLE #1: Thu May 19 15:05:33 EEST 2011 - 
2748140 ierrors in 20 hours uptime - ~250Mb/s bandwidth

10.)8.1-STABLE FreeBSD 8.1-STABLE #0: Thu Aug 19 13:49:35 EEST 2010 - no 
ierrors - bandwidth usage as server 1

11.)7.2-STABLE FreeBSD 7.2-STABLE #1: Fri Dec 11 15:26:14 EET 2009 - 2 
interfaces - 1835 ierrors since boot, 5392022 errors since boot - 
~80Mb/s bandwidth

12.)8.0-STABLE FreeBSD 8.0-STABLE #0: Tue May 11 13:58:54 EEST 2010 - 
114 ierrors since boot - bandwidth usage as server 1

13.) 7.4-STABLE FreeBSD 7.4-STABLE #3: Thu Jun  2 10:56:15 EEST 2011 - 
no ierrors - bandwidth usage as server 1

14.)8.0-STABLE FreeBSD 8.0-STABLE #1: Wed Jan  6 17:57:14 EET 2010 - no 
ierrors - bandwidth usage as server 1

Also on the same switch are servers with FreeBSD amd64 with BCM5702X 
(bge driver) - small bandwidth usage ~65000 input errors
