The default value for this parameter is 50, which is quite low for many of today's uses and the only way to modify this parameter right now is to edit if_var.h file. Also add read-only sysctl with the same name, so that it's possible to retrieve the current value. 2009-06-09T07:14:32Z Warner Losh imp@FreeBSD.org 2009-06-09T07:14:32Z urn:sha1:2b9a8a330fa9729f18534a8a0b5a42d39fd24b61 2009-02-15T23:29:13Z Robert Watson rwatson@FreeBSD.org 2009-02-15T23:29:13Z urn:sha1:cdb31d3351c610914d974f3063ca545c4ae61430 stack with conditional Giant acquisition, and IFF_NEEDSGIANT will be removed in the near future. 2008-10-23T15:53:51Z Dag-Erling Smørgrav des@FreeBSD.org 2008-10-23T15:53:51Z urn:sha1:1ede983cc905643549d8cae56a9d0e28fc68375f MFC after: 3 months 2008-09-27T08:51:18Z Ed Schouten ed@FreeBSD.org 2008-09-27T08:51:18Z urn:sha1:6bfa9a2d66dd0e00182017d6741d44e54d0b2cca After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere. This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past. I suspect not many people connect more than 256 pieces of the same hardware.

Many remaining references to NET_.*_GIANT() and NET_CALLOUT_MPSAFE are still present in subsystems, and will be removed in followup commits.
