Subject: net: gem: Allocate BD_SPACE in connection to RX_BUF
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e8c52f97bc58b2dc207d60fafe4b07a80a385510;p=thirdparty%2Fu-boot.git

net: gem: Allocate BD_SPACE in connection to RX_BUF

BD_SEPRN_SPACE should not have hard coded value and it will be
calculated based on the number of buffer descriptors that we
would like to use.
