Subject: igb: resolve warning of unused adapter struct
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bd38e5d124ddd11c457c5ae7242cd039045d80e0;p=linux-beck.git

igb: resolve warning of unused adapter struct

If DCA is undefined then the adapter struct becomes unnecessary.  To
resolve this issue the DCA calls can simply make a call to the adapter
struct through the rx_ring adapter struct member.
