New Revision: 247822
URL: http://svnweb.freebsd.org/changeset/base/247822
Log:
First, sync to internal shared code, and then
Fixes:
- flow control - don't override user value on re-init
- fix to make 1G optics work correctly
- change to interrupt enabling - some bits were incorrect
for certain hardware.
- certain stats fixes, remove a duplicate increment of
ierror, thanks to Scott Long for pointing these out.
- shared code link interface changed, requiring some
core code changes to accomodate this.
- add an m_adj() to ETHER_ALIGN on the recieve side, this
was requested by Mike Karels, thanks Mike.
- Multicast code corrections also thanks to Mike Karels.
